A statistics object located in a temporary schema cannot be named without schema qualification, but pg_statistics_obj_is_visible() missed that memo and could return “true” regardless. In turn, functions such as pg_describe_object() could fail to schema-qualify the object's name as expected.

The risk here is that an attacker who has gained superuser-level control over the source server might be able to cause it to emit text that would be interpreted as psql meta-commands. That would provide shell-level access to the restoring user's own account, independently of access to the target database.
\nTo provide a positive guarantee that this can't happen, extend psql with a \\restrict command that prevents execution of further meta-commands, and teach pg_dump to issue that before any data coming from the source server.

\nWhen choosing an auto-generated name for an index, avoid conflicting with not-yet-committed pg_class rows as well as fully-valid ones. This avoids possibly choosing the same name as some concurrent CREATE INDEX did, when that command is still in process of filling its index, or is done but is part of a not-yet-committed transaction. There's still a window for trouble, but it's only as long as the time needed to validate a new index's parameters and insert its pg_class row.
Prevent usage of incorrect VACUUM options in some cases where multiple tables are vacuumed in a single command (Nathan Bossart, Michael Paquier) §
The TRUNCATE and INDEX_CLEANUP options of one table could be applied to others.
Fix processing of character classes within SIMILAR TO regular expressions (Laurenz Albe) § §
The code that translates SIMILAR TO pattern matching expressions to POSIX-style regular expressions did not consider that square brackets can be nested. For example, in a pattern like [[:alpha:]%_], the code treated the % and _ characters as metacharacters when they should be literals.

PostgreSQL header files generally need to be wrapped in extern \"C\" { ... } in order to be included in extensions written in C++.

C++ extensions that want to use libicu's C++ APIs can do so by including the libicu headers ahead of pg_locale.h.
A dump/restore is not required for those running 13.X.
\nHowever, if you have any self-referential foreign key constraints on partitioned tables, it may be necessary to recreate those constraints to ensure that they are being enforced correctly. See the second changelog entry below.

In PL/pgSQL, avoid “unexpected plan node type” error when a scrollable cursor is defined on a simple SELECT query (Andrei Lepikhov) §expression
Don't try to drop individual index partitions in pg_dump's --clean mode (Jian He) §
The server rejects such DROP commands. That has no real consequences, since the partitions will go away anyway in the subsequent DROPs of either their parent tables or their partitioned index. However, the error reported for the attempted drop causes problems when restoring in --single-transaction mode.
In pg_dumpall, avoid emitting invalid role GRANT commands if pg_auth_members contains invalid role OIDs (Tom Lane) §
Instead, print a warning and skip the entry. This copes better with catalog corruption that has been seen to occur in back branches as a result of race conditions between GRANT and DROP ROLE.
Allow contrib/dblink queries to be interrupted by query cancel (Noah Misch) § §
This change back-patches a v17-era fix. It prevents possible hangs in CREATE DATABASE and DROP DATABASE due to failure to detect deadlocks.
Avoid crashing with corrupt input data in contrib/pageinspect's heap_page_items() (Dmitry Kovalenko) §
Prevent assertion failure in contrib/pg_freespacemap's pg_freespacemap() (Tender Wang) §
Applying pg_freespacemap() to a relation lacking storage (such as a view) caused an assertion failure, although there was no ill effect in non-assert builds. Add an error check to reject that case.
Fix build failure on macOS 15.4 (Tom Lane, Peter Eisentraut) §

\nDo not check datallowconn, rolcanlogin, and ACL_CONNECT privileges when starting a parallel worker, instead assuming that it's enough for the leader process to have passed similar checks originally. This avoids, for example, unexpected failures of parallelized queries when the leader is running as a role that lacks login privilege. In the same vein, enforce ReservedConnections, datconnlimit, and rolconnlimit limits only against regular backends, and count only regular backends while checking if the limits were already reached. Those limits are meant to prevent excessive consumption of process slots for regular backends --- but parallel workers and other special processes have their own pools of process slots with their own limit checks.

Fix incorrect tg_updatedcols values passed to AFTER UPDATE triggers (Tom Lane) §
In some cases the tg_updatedcols bitmap could describe the set of columns updated by an earlier command in the same transaction, fooling the trigger into doing the wrong thing.
Also, prevent memory bloat caused by making too many copies of the tg_updatedcols bitmap.

An integer format code immediately preceding FF would consume all available digits, leaving none for nFF.n

Don't merge UNION operations if their column collations aren't consistent (Tom Lane) §
Previously we ignored collations when deciding if it's safe to merge UNION steps into a single N-way UNION operation. This was arguably valid before the introduction of nondeterministic collations, but it's not anymore, since the collation in use can affect the definition of uniqueness.

\nIn some cases a data type could be dropped while references to its OID still remain in pg_amop or pg_amproc. While that caused no immediate issues, an attempt to drop the owning operator family would fail, and pg_dump would produce bogus output when dumping the operator family. This fix causes creation and modification of operator families/classes to add needed dependency entries so that dropping a data type will also drop any dependent operator family elements. That does not help vulnerable pre-existing operator families, though, so a band-aid has also been added to DROP OPERATOR FAMILY to prevent failure when dropping a family that has dangling members.

Avoid integer overflow while testing wal_skip_threshold condition (Tom Lane) §
A transaction that created a very large relation could mistakenly decide to ensure durability by copying the relation into WAL instead of fsync'ing it, thereby negating the point of wal_skip_threshold. (This only matters when wal_level is set to minimal, else a WAL copy is required anyway.)
Fix unsafe order of operations during cache lookups (Noah Misch) §
\nThe only known consequence was a usually-harmless “you don't own a lock of type ExclusiveLock” warning during GRANT TABLESPACE.
Fix possible “failed to resolve name” failures when using JIT on older ARM platforms (Thomas Munro) §
\nThis could occur as a consequence of inconsistency about the default setting of -moutline-atomics between gcc and clang. At least Debian and Ubuntu are known to ship gcc and clang compilers that target armv8-a but differ on the use of outline atomics by default.
Fix handling of Windows junction points that are not of PostgreSQL origin (Thomas Munro) § §

The equality function could modify or delete the object if it's given a read-write pointer, which would be bad if we decide to return it as the NULLIF() result. There is probably no problem with any built-in equality function, but it's easy to demonstrate a failure with one coded in PL/pgSQL.

\nRepeated use of PLyPlan.execute or plpy.cursor resulted in memory leakage for the duration of the calling PL/Python function.

\nSome two-byte characters in SJIS have a second byte that is equal to ASCII backslash (\\). These characters were corrupted by path name normalization, preventing access to files whose names include such characters.
Fix use of wrong version of pqsignal() in pgbench and psql (Fujii Masao, Tom Lane) §
This error could lead to misbehavior when using the -T option in pgbench or the \\watch command in psql, due to interrupted system calls not being resumed as expected.
Fix misexecution of some nested \\if constructs in pgbench (Michail Nikolaev) §

Update configuration probes that determine the compiler switches needed to access ARM CRC instructions (Tom Lane) §
\nOn ARM platforms where the baseline CPU target lacks CRC instructions, we need to supply a -march switch to persuade the compiler to compile such instructions. Recent versions of gcc reject the value we were trying, leading to silently falling back to software CRC.
During configure, if a C23 compiler is detected, try asking for C17 (Thomas Munro) §
\nPostgreSQL versions before v16 will not compile under C23 rules. If the chosen compiler defaults to C23 or later, try adding a -std=gnu17 switch to change that. (If this won't work for your compiler, manually specify CFLAGS with a suitable switch.)

This is bad, since for example WAL files might have been removed on the basis of the later restart_lsn value, in which case replication would fail to restart.
Count index scans in contrib/bloom indexes in the statistics views, such as the pg_stat_user_indexes.idx_scan counter (Masahiro Ikeda) §
Fix crash when checking to see if an index's opclass options have changed (Alexander Korotkov) §
\nSome forms of ALTER TABLE would fail if the table has an index with non-default operator class options.
A dump/restore is not required for those running 13.X.
\nHowever, if you have ever detached a partition from a partitioned table that has a foreign-key reference to another partitioned table, and not dropped the former partition, then you may have catalog and/or data corruption to repair, as detailed in the fifth changelog entry below.
\nAlso, if you are upgrading from a version earlier than 13.14, see Section E.10.

foreign-key constraints when attaching or detaching table partitions (Jehan-Guillaume de Rorthais, Tender Wang, Álvaro Herrera) §
\nIf the referenced table is partitioned, then different catalog entries are needed for a referencing table that is stand-alone versus one that is a partition. ATTACH/DETACH PARTITION commands failed to perform this conversion correctly. In particular, after DETACH the now stand-alone table would be missing foreign-key enforcement triggers, which could result in the table later containing rows that fail the foreign-key constraint. A subsequent re-ATTACH could fail with surprising errors, too.
The way to fix this is to do ALTER TABLE DROP CONSTRAINT on the now stand-alone table for each faulty constraint, and then re-add the constraint. If re-adding the constraint fails, then some erroneous data has crept in. You will need to manually re-establish consistency between the referencing and referenced tables, then re-add the constraint.
This query can be used to identify broken constraints and construct the commands needed to recreate them:
\nSELECT conrelid::pg_catalog.regclass AS \"constrained table\",\n conname AS constraint,\n confrelid::pg_catalog.regclass AS \"references\",\n pg_catalog.format('ALTER TABLE %s DROP CONSTRAINT %I;',\n conrelid::pg_catalog.regclass, conname) AS \"drop\",\n pg_catalog.format('ALTER TABLE %s ADD CONSTRAINT %I %s;',\n conrelid::pg_catalog.regclass, conname,\n pg_catalog.pg_get_constraintdef(oid)) AS \"add\"\nFROM pg_catalog.pg_constraint c\nWHERE contype = 'f' AND conparentid = 0 AND\n (SELECT count(*) FROM pg_catalog.pg_constraint c2\n WHERE c2.conparentid = c.oid) <>\n ((SELECT count(*) FROM pg_catalog.pg_inherits i\n WHERE (i.inhparent = c.conrelid OR i.inhparent = c.confrelid) AND\n EXISTS (SELECT 1 FROM pg_catalog.pg_partitioned_table\n WHERE partrelid = i.inhparent)) +\n CASE WHEN pg_catalog.pg_partition_root(conrelid) = confrelid THEN\n (SELECT count(*) FROM pg_catalog.pg_partition_tree(confrelid)\n WHERE level = 1)\n ELSE 0 END);\n\nSince it is possible that one or more of the ADD CONSTRAINT steps will fail, you should save the query's output in a file and then attempt to perform each step.

\nNormal row updates write a new version of the row to preserve rollback-ability of the transaction. However, certain system catalog updates are intentionally non-transactional and are done with an in-place update of the row. These patches fix race conditions that could cause the effects of an in-place update to be lost. As an example, it was possible to forget having set pg_class.relhasindex to true, preventing updates of the new index and thus causing index corruption.
Reset catalog caches at end of recovery (Noah Misch) §
\nThis prevents scenarios wherein an in-place catalog update could be lost due to using stale data from a catalog cache.

Fix “failed to find plan for subquery/CTE” errors in EXPLAIN (Richard Guo, Tom Lane) § §
This case arose while trying to print references to fields of a RECORD-type output of a subquery when the subquery has been optimized out of the plan altogether (which is possible at least in the case that it has a constant-false WHERE condition). Nothing remains in the plan to identify the original field names, so fall back to printing f for the NN'th record column. (That's actually the right thing anyway, if the record output arose from a ROW() constructor.)
Disallow a USING clause when altering the type of a generated column (Peter Eisentraut) §
A generated column already has an expression specifying the column contents, so including USING doesn't make sense.
Ignore not-yet-defined Portals in the pg_cursors view (Tom Lane) §
It is possible for user-defined code that inspects this view to be called while a new cursor is being set up, and if that happens a null pointer dereference would ensue. Avoid the problem by defining the view to exclude incompletely-set-up cursors.

\nThis tzdata release changes the old System-V-compatibility zone names to duplicate the corresponding geographic zones; for example PST8PDT is now an alias for America/Los_Angeles. The main visible consequence is that for timestamps before the introduction of standardized time zones, the zone is considered to represent local mean solar time for the named location. For example, in PST8PDT, timestamptz input such as 1801-01-01 00:00 would previously have been rendered as 1801-01-01 00:00:00-08, but now it is rendered as 1801-01-01 00:00:00-07:52:58.
Also, historical corrections for Mexico, Mongolia, and Portugal. Notably, Asia/Choibalsan is now an alias for Asia/Ulaanbaatar rather than being a separate zone, mainly because the differences between those zones were found to be based on untrustworthy data.
A dump/restore is not required for those running 13.X.
\nHowever, if you are upgrading from a version earlier than 13.14, see Section E.10.

\nAn attacker able to create and drop non-temporary objects could inject SQL code that would be executed by a concurrent pg_dump session with the privileges of the role running pg_dump (which is often a superuser). The attack involves replacing a sequence or similar object with a view or foreign table that will execute malicious code. To prevent this, introduce a new server parameter restrict_nonsystem_relation_kind that can disable expansion of non-builtin views as well as access to foreign tables, and teach pg_dump to set it when available. Note that the attack is prevented only if both pg_dump and the server it is dumping from are new enough to have this fix.

When a partitioned table has an index that is not associated with a constraint, but a partition has an equivalent index that is, then detaching the partition would misbehave, leaving the ex-partition's constraint with an incorrect coninhcount value. This would cause trouble during any further manipulations of that constraint.
Fix handling of polymorphic output arguments for procedures (Tom Lane) § §
\nThe SQL CALL statement did not resolve the correct data types for such arguments, leading to errors such as “cannot display a value of type anyelement”, or even outright crashes. (But CALL in PL/pgSQL worked correctly.)
Fix behavior of stable functions called from a CALL statement's argument list (Tom Lane) §
If the CALL is within an atomic context (e.g. there's an outer transaction block), such functions were passed the wrong snapshot, causing them to see stale values of rows modified since the start of the outer transaction.
Detect integer overflow in money calculations (Joseph Koshakow) §
None of the arithmetic functions for the money type checked for overflow before, so they would silently give wrong answers for overflowing cases.
Fix over-aggressive clamping of the scale argument in round(numeric) and trunc(numeric) (Dean Rasheed) §
These functions clamped their scale argument to +/-2000, but there are valid use-cases for it to be larger; the functions returned incorrect results in such cases. Instead clamp to the actual allowed range of type numeric.

Detect another integer overflow case while computing new array dimensions (Joseph Koshakow) §
\nReject applying array dimensions [-2147483648:2147483647] to an empty array. This is closely related to CVE-2023-5869, but appears harmless since the array still ends up empty.
Detect another case of a new catalog cache entry becoming stale while detoasting its fields (Noah Misch) §
\nAn in-place update occurring while we expand out-of-line fields in a catalog tuple could be missed, leading to a catalog cache entry that lacks the in-place change but is not known to be stale. This is only possible in the pg_database catalog, so the effects are narrow, but misbehavior is possible.
Correctly check updatability of view columns targeted by INSERT ... DEFAULT (Tom Lane) §
If such a column is non-updatable, we should give an error reporting that. But the check was missed and then later code would report an unhelpful error such as “attribute number N not found in view targetlist”.
Avoid reporting an unhelpful internal error for incorrect recursive queries (Tom Lane) §
\nRearrange the order of error checks so that we throw an on-point error when a WITH RECURSIVE query does not have a self-reference within the second arm of the UNION, but does have one self-reference in some other place such as ORDER BY.
Don't throw an error if a queued AFTER trigger no longer exists (Tom Lane) §
It's possible for a transaction to execute an operation that queues a deferred AFTER trigger for later execution, and then to drop the trigger before that happens. Formerly this led to weird errors such as “could not find trigger NNNN”. It seems better to silently do nothing if the trigger no longer exists at the time when it would have been executed.
Fix failure to remove pg_init_privs entries for column-level privileges when their table is dropped (Tom Lane) §

\nIn versions before PostgreSQL 16, it was possible for generated conditions to be evaluated below outer joins when they should be evaluated above (after) the outer join, leading to incorrect query results. All versions have a similar hazard when considering joins to UNION ALL trees that have constant outputs for the join column in some SELECT arms.
Avoid unnecessary use of moving-aggregate mode with a non-moving window frame (Vallimaharajan G) §
\nWhen a plain aggregate is used as a window function, and the window frame start is specified as UNBOUNDED PRECEDING, the frame's head cannot move so we do not need to use the special (and more expensive) moving-aggregate mode. This optimization was intended all along, but due to a coding error it never triggered.

Be more careful with RECORD-returning functions in FROM (Tom Lane) § §
The output columns of such a function call must be defined by an AS clause that specifies the column names and data types. If the actual function output value doesn't match that, an error is supposed to be thrown at runtime. However, some code paths would examine the actual value prematurely, and potentially issue strange errors or suffer assertion failures if it doesn't match expectations.

This could occur in cases involving UNION ALL with constant-emitting subqueries. Sorting by a constant is useless of course, but it also risks being misinterpreted by the remote server, leading to “ORDER BY position N is not in select list” errors.
Make contrib/postgres_fdw set the remote session's time zone to GMT not UTC (Tom Lane) §
This should have the same results for practical purposes. However, GMT is recognized by hard-wired code in the server, while UTC is looked up in the timezone database. So the old code could fail in the unlikely event that the remote server's timezone database is missing entries.

Properly lock the associated table during DROP STATISTICS (Tomas Vondra) §
Failure to acquire the lock could result in “tuple concurrently deleted” errors if the DROP executes concurrently with ANALYZE.
Fix function volatility checking for GENERATED and DEFAULT expressions (Tom Lane) §
These places could fail to detect insertion of a volatile function default-argument expression, or decide that a polymorphic function is volatile although it is actually immutable on the datatype of interest. This could lead to improperly rejecting or accepting a GENERATED clause, or to mistakenly applying the constant-default-value optimization in ALTER TABLE ADD COLUMN.
Detect that a new catalog cache entry became stale while detoasting its fields (Tom Lane) § §
\nWe expand any out-of-line fields in a catalog tuple before inserting it into the catalog caches. That involves database access which might cause invalidation of catalog cache entries — but the new entry isn't in the cache yet, so we would miss noticing that it should get invalidated. The result is a race condition in which an already-stale cache entry could get made, and then persist indefinitely. This would lead to hard-to-predict misbehavior. Fix by rechecking the tuple's visibility after detoasting.

Prevent standby servers from incorrectly processing dead index tuples during subtransactions (Fei Changhong) §
\nThe startedInRecovery flag was not correctly set for a subtransaction. This affects only processing of dead index tuples. It could allow a query in a subtransaction to ignore index entries that it should return (if they are already dead on the primary server, but not dead to the standby transaction), or to prematurely mark index entries as dead that are not yet dead on the primary. It is not clear that the latter case has any serious consequences, but it's not the intended behavior.

There are interval values that are distinguishable but compare equal, for example 24:00:00 and 1 day. This breaks assumptions made by btree de-duplication, so interval columns need to be excluded from de-duplication. This oversight can cause incorrect results from index-only scans. Moreover, after updating amcheck will report an error for almost all such indexes. Users should reindex any btree indexes on interval columns.
Fix partition step generation and runtime partition pruning for hash-partitioned tables with multiple partition keys (David Rowley) § §
\nSome cases involving an IS NULL condition on one of the partition keys could result in a crash.
Fix edge case in btree mark/restore processing of ScalarArrayOpExpr clauses (Peter Geoghegan) §
\nWhen restoring an indexscan to a previously marked position, the code could miss required setup steps if the scan had advanced exactly to the end of the matches for a ScalarArrayOpExpr (that is, an indexcol = ANY(ARRAY[])) clause. This could result in missing some rows that should have been fetched.

\nReport an error if pgstatindex(), pgstatginindex(), pgstathashindex(), or pgstattuple() is applied to an invalid index. If brin_desummarize_range(), brin_summarize_new_values(), brin_summarize_range(), or gin_clean_pending_list() is applied to an invalid index, do nothing except to report a debug-level message. Formerly these functions attempted to process the index, and might fail in strange ways depending on what the failed CREATE INDEX had left behind.
Avoid premature memory allocation failure with long inputs to to_tsvector() (Tom Lane) §
Fix over-allocation of the constructed tsvector in tsvectorrecv() (Denis Erokhin) §
If the incoming vector includes position data, the binary receive function left wasted space (roughly equal to the size of the position data) in the finished tsvector. In extreme cases this could lead to “maximum total lexeme length exceeded” failures for vectors that were under the length limit when emitted. In any case it could lead to wasted space on-disk.
Fix incorrect coding in gtsvector_picksplit() (Alexander Lakhin) §
This could lead to poor page-split decisions in GiST indexes on tsvector columns.

Avoid improper response to shutdown signals in child processes just forked by system() (Nathan Bossart) § §
This fix avoids a race condition in which a child process that has been forked off by system(), but hasn't yet exec'd the intended child program, might receive and act on a signal intended for the parent server process. That would lead to duplicate cleanup actions being performed, which will not end well.
Cope with torn reads of pg_control in frontend programs (Thomas Munro) §
On some file systems, reading pg_control may not be an atomic action when the server concurrently writes that file. This is detectable via a bad CRC. Retry a few times to see if the file becomes valid before we report error.
Avoid torn reads of pg_control in relevant SQL functions (Thomas Munro) §
Acquire the appropriate lock before reading pg_control, to ensure we get a consistent view of that file.
Avoid integer overflow when computing size of backend activity string array (Jakub Wartak) §
\nOn 64-bit machines we will allow values of track_activity_query_size large enough to cause 32-bit overflow when multiplied by the allowed number of connections. The code actually allocating the per-backend local array was careless about this though, and allocated the array incorrectly.

\nXcode 15 (released with macOS Sonoma) changed the linker's behavior in a way that causes many duplicate-library warnings while building PostgreSQL. These were harmless, but they're annoying so avoid citing the same libraries twice. Also remove use of the -multiply_defined suppress linker switch, which apparently has been a no-op for a long time, and is now actively complained of.
When building contrib/unaccent's rules file, fall back to using python if --with-python was not given and make variable PYTHON was not set (Japin Li) §
Remove PHOT (Phoenix Islands Time) from the default timezone abbreviations list (Tom Lane) §
Presence of this abbreviation in the default list can cause failures on recent Debian and Ubuntu releases, as they no longer install the underlying tzdb entry by default. Since this is a made-up abbreviation for a zone with a total human population of about two dozen, it seems unlikely that anyone will miss it.

\nEach of these oversights could result in forgetting that a BRIN index range contains any NULL values, potentially allowing subsequent queries that should return NULL values to miss doing so.
\nThis fix will not in itself correct faulty BRIN entries. It's recommended to REINDEX any BRIN indexes that may be used to search for nulls.
Avoid leaving a corrupted database behind when DROP DATABASE is interrupted (Andres Freund) §
If DROP DATABASE was interrupted after it had already begun taking irreversible steps, the target database remained accessible (because the removal of its pg_database row would roll back), but it would have corrupt contents. Fix by marking the database as inaccessible before we begin to perform irreversible operations. A failure after that will leave the database still partially present, but nothing can be done with it except to issue another DROP DATABASE.

Fix race condition in per-batch cleanup during parallel hash join (Thomas Munro, Melanie Plageman) §
\nA crash was possible given unlucky timing and parallel_leader_participation = off (which is not the default).
Recalculate GENERATED columns after an EvalPlanQual check (Tom Lane) §
In READ COMMITTED isolation mode, the effects of a row update might need to get reapplied to a newer version of the row than the query found originally. If so, we need to recompute any GENERATED columns, in case they depend on columns that were changed by the concurrent update.
Don't balance vacuum cost delay when a table has a per-relation vacuum_cost_delay setting of zero (Masahiko Sawada) §
Delay balancing is supposed to be disabled whenever autovacuum is processing a table with a per-relation vacuum_cost_delay setting, but this was done only for positive settings, not zero.

With gssencmode set to require, the connection was not marked dead after a GSS initialization failure. Make it fail immediately, as the equivalent case for TLS encryption has long done.
Fix possible data corruption in ecpg programs built with the -C ORACLE option (Kyotaro Horiguchi) §
When ecpg_get_data() is called with varcharsize set to zero, it could write a terminating zero character into the last byte of the preceding field, truncating the data in that field.
Fix pg_dump so that partitioned tables that are hash-partitioned on an enum-type column can be restored successfully (Tom Lane) §
\nSince the hash codes for enum values depend on the OIDs assigned to the enum, they are typically different after a dump and restore, meaning that rows often need to go into a different partition than they were in originally. Users can work around that by specifying the --load-via-partition-root option; but since there is very little chance of success without that, teach pg_dump to apply it automatically to such tables.
Also, fix pg_restore to not try to TRUNCATE target tables before restoring into them when --load-via-partition-root mode is used. This avoids a hazard of deadlocks and lost data.

A regex such as $foo is legal but unsatisfiable; the regex compiler recognizes that and produces an empty NFA graph. Attempting to optimize such a graph into a pg_trgm GIN or GiST index qualification resulted in accessing off the end of a work array, possibly leading to crashes.
Use the --strip-unneeded option when stripping static libraries with GNU-compatible strip (Tom Lane) §
Previously, make install-strip used the -x option in this case. This change avoids misbehavior of llvm-strip, and gives slightly smaller output as well.
Stop recommending auto-download of DTD files for building the documentation, and indeed disable it (Aleksander Alekseev, Peter Eisentraut, Tom Lane) §
\nIt appears no longer possible to build the SGML documentation without a local installation of the DocBook DTD files. Formerly xsltproc could download those files on-the-fly from sourceforge.net; but sourceforge.net now permits only HTTPS access, and no common version of xsltproc supports that. Hence, remove the bits of our documentation suggesting that that's possible or useful, and instead add xsltproc's --nonet option to the build recipes.
When running TAP tests in PGXS builds, use a saner location for the temporary portlock directory (Peter Eisentraut) §
Place it under tmp_check in the build directory. With the previous coding, a PGXS build would try to place it in the installation directory, which is not necessarily writable.
Update time zone data files to tzdata release 2023c for DST law changes in Egypt, Greenland, Morocco, and Palestine. (Tom Lane) §

Also, America/Yellowknife is no longer distinct from America/Edmonton; this affects some pre-1948 timestamps in that area.

This fixes failure to update GENERATED columns that do not exist in the parent table, or that have different dependencies than are in the parent column's generation expression.
Allow REPLICA IDENTITY to be set on an index that's not (yet) valid (Tom Lane) §
When pg_dump dumps a partitioned index that's marked REPLICA IDENTITY, it generates a command sequence that applies REPLICA IDENTITY before the partitioned index has been marked valid, causing restore to fail. There seems no very good reason to prohibit doing it in that order, so allow it. The marking will have no effect anyway until the index becomes valid.
Fix handling of DEFAULT markers in rules that perform an INSERT from a multi-row VALUES list (Dean Rasheed) §
In some cases a DEFAULT marker would not get replaced with the proper default-value expression, leading to an “unrecognized node type” error.
Reject uses of undefined variables in jsonpath existence checks (Alexander Korotkov, David G. Johnston) §
While jsonpath match operators threw an error for an undefined variable in the path pattern, the existence operators silently treated it as a match.

\nThe previous coding leaked the connection object. In background code paths that's pretty harmless because the calling process will give up and exit. But in commands such as CREATE SUBSCRIPTION, such a failure resulted in a small session-lifespan memory leak.
In hot-standby servers, reduce processing effort for tracking XIDs known to be active on the primary (Simon Riggs, Michail Nikolaev) §
\nInsufficiently-aggressive cleanup of the KnownAssignedXids array could lead to poor performance, particularly when max_connections is set to a large value on the standby.
Ignore invalidated logical-replication slots while determining oldest catalog xmin (Sirisha Chamarthi) §
\nA replication slot could prevent cleanup of dead tuples in the system catalogs even after it becomes invalidated due to exceeding max_slot_wal_keep_size. Thus, failure of a replication consumer could lead to indefinitely-large catalog bloat.

Given the right circumstances, this manifested as a “tupdesc reference NNNN is not owned by resource owner” error followed by a PANIC exit.
Repair rare failure of MULTIEXPR_SUBLINK subplans in inherited updates (Tom Lane) § § §
\nUse of the syntax UPDATE tab SET (c1, ...) = (SELECT ...) with an inherited or partitioned target table could result in failure if the child tables are sufficiently dissimilar. This typically manifested as failure of consistency checks in the executor; but a crash or incorrect data updates are also possible.

Build a separate function cache entry for each concrete type passed to the RECORD parameter during a session, much as we do for polymorphic parameters. This allows some usages to work that previously failed with errors such as “type of parameter does not match that when preparing the plan”.
Add missing guards for NULL connection pointer in libpq (Daniele Varrazzo, Tom Lane) §
There's a convention that libpq functions should check for a NULL PGconn argument, and fail gracefully instead of crashing. PQflush() and PQisnonblocking() didn't get that memo, so fix them.
In ecpg, fix omission of variable storage classes when multiple varchar or bytea variables are declared in the same declaration (Andrey Sokolov) §
For example, ecpg translated static varchar str1[10], str2[20], str3[30]; in such a way that only str1 was marked static.
Allow cross-platform tablespace relocation in pg_basebackup (Robert Haas) §
\nAllow the remote path in --tablespace-mapping to be either a Unix-style or Windows-style absolute path, since the source server could be on a different OS than the local system.
In pg_stat_statements, fix access to already-freed memory (zhaoqigui) §
\nThis occurred if pg_stat_statements tracked a ROLLBACK command issued via extended query protocol. In debug builds it consistently led to an assertion failure. In production builds there would often be no visible ill effect; but if the freed memory had already been reused, the likely result would be to store garbage for the query string.

The uuid-ossp module expects libc's uuid_create() to produce a version-1 UUID, but recent NetBSD releases produce a version-4 (random) UUID instead. Check for that, and complain if so. Drop the documentation's claim that the NetBSD implementation is usable for uuid-ossp. (If a version-4 UUID is okay for your purposes, you don't need uuid-ossp at all; just use gen_random_uuid().)
Include new Perl test modules in standard installations (Álvaro Herrera) §
\nAdd PostgreSQL/Test/Cluster.pm and PostgreSQL/Test/Utils.pm to the standard installation file set in pre-version-15 branches. This is for the benefit of extensions that want to use newly-written test code in older branches.

(Tom Lane) §
\nAlso, the Europe/Kiev zone has been renamed to Europe/Kyiv. Also, the following zones have been merged into nearby, more-populous zones whose clocks have agreed with them since 1970: Antarctica/Vostok, Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake and Pacific/Wallis. (This indirectly affects zones that were already links to one of these: Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape, Pacific/Truk, and Pacific/Yap.) America/Nipigon, America/Rainy_River, America/Thunder_Bay, Europe/Uzhgorod, and Europe/Zaporozhye were also merged into nearby zones after discovering that their claimed post-1970 differences from those zones seem to have been errors. In all these cases, the previous zone name remains as an alias; but the actual data is that of the zone that was merged into.
\nThese zone mergers result in loss of pre-1970 timezone history for the merged zones, which may be troublesome for applications expecting consistency of timestamptz display. As an example, the stored value 1944-06-01 12:00 UTC would previously display as 1944-06-01 13:00:00+01 if the Europe/Stockholm zone is selected, but now it will read out as 1944-06-01 14:00:00+02.
It is possible to build the time zone data files with options that will restore the older zone data, but that choice also inserts a lot of other old (and typically poorly-attested) zone data, resulting in more total changes from the previous release than accepting these upstream changes does. PostgreSQL has chosen to ship the tzdb data as-recommended, and so far as we are aware most major operating system distributions are doing likewise. However, if these changes cause significant problems for your application, a possible solution is to install a local build of the time zone data files using tzdb's backwards-compatibility options (see their PACKRATDATA and PACKRATLIST options).
A dump/restore is not required for those running 13.X.
\nHowever, if you are upgrading from a version earlier than 13.7, see Section E.17.

\nNormally a Postgres tablespace is a symbolic link to a directory on some other filesystem. This change allows it to just be a plain directory. While this has no use for separating tables onto different filesystems, it is a convenient setup for testing. Moreover, it is necessary to support the CREATE DATABASE replay fix, which transiently creates a missing tablespace as an “in place” tablespace.
Fix permissions checks in CREATE INDEX (Nathan Bossart, Noah Misch) §
The fix for CVE-2022-1552 caused CREATE INDEX to apply the table owner's permissions while performing lookups of operator classes and other objects, where formerly the calling user's permissions were used. This broke dump/restore scenarios, because pg_dump issues CREATE INDEX before re-granting permissions.
In extended query protocol, force an immediate commit after CREATE DATABASE and other commands that can't run in a transaction block (Tom Lane) §
If the client does not send a Sync message immediately after such a command, but instead sends another command, any failure in that command would lead to rolling back the preceding command, typically leaving inconsistent state on-disk (such as a missing or extra database directory). The mechanisms intended to prevent that situation turn out to work for multiple commands in a simple-Query message, but not for a series of extended-protocol messages. To prevent inconsistency without breaking use-cases that work today, force an implicit commit after such commands.

The default signature length (hash size) for GiST indexes on ltree columns was accidentally changed while upgrading that operator class to support operator class parameters. If any operations had been done on such an index without first upgrading the ltree extension to version 1.2, they were done assuming that the signature length was 28 bytes rather than the intended 8. This means it is very likely that such indexes are now corrupt. For safety we recommend re-indexing all GiST indexes on ltree columns after installing this update. (Note that GiST indexes on ltree[] columns, that is arrays of ltree, are not affected.)
Stop using query-provided column aliases for the columns of whole-row variables that refer to plain tables (Tom Lane) §
\nThe column names in tuples produced by a whole-row variable (such as tbl.* in contexts other than the top level of a SELECT list) are now always those of the associated named composite type, if there is one. We'd previously attempted to make them track any column aliases that had been applied to the FROM entry the variable refers to. But that's semantically dubious, because really then the output of the variable is not at all of the composite type it claims to be. Previous attempts to deal with that inconsistency had bad results up to and including storing unreadable data on disk, so just give up on the whole idea.
In cases where it's important to be able to relabel such columns, a workaround is to introduce an extra level of sub-SELECT, so that the whole-row variable is referring to the sub-SELECT's output and not to a plain table. Then the variable is of type record to begin with and there's no issue.

\nThis change synchronizes libpq's rules for safe ownership and permissions of SSL key files with the rules the server has used since release 9.6. Namely, in addition to the current rules, allow the case where the key file is owned by root and has permissions rw-r----- or less. This is helpful for system-wide management of key files.
Fix behavior of libpq's PQisBusy() function after a connection failure (Tom Lane) §
If we'd detected a write failure, PQisBusy() would always return true, which is the wrong thing: we want input processing to carry on normally until we've read whatever is available from the server. The practical effect of this error is that applications using libpq's async-query API would typically detect connection loss only when PQconsumeInput() returns a hard failure. With this fix, a connection loss will normally be reported via an error PGresult object, which is a much cleaner behavior for most applications.
Make pg_ctl recheck postmaster aliveness while waiting for stop/restart/promote actions (Tom Lane) §
\npg_ctl would verify that the postmaster is alive as a side-effect of sending the stop or promote signal, but then it just naively waited to see the on-disk state change. If the postmaster died uncleanly without having removed its PID file or updated the control file, pg_ctl would wait until timeout. Instead make it recheck every so often that the postmaster process is still there.

If applied to a TOAST table or TOAST table's index, REINDEX CONCURRENTLY tended to produce a corrupted index. This happened because sessions updating TOAST entries released their ROW EXCLUSIVE locks immediately, rather than holding them until transaction commit as all other updates do. The fix is to make TOAST updates hold the table lock according to the normal rule. Any existing corrupted indexes can be repaired by reindexing again.

Index-only scans returned column values with trailing spaces removed, which is not the expected behavior. That happened because that's how the data was stored in the index. This fix changes the code to store char( values with the expected amount of space padding. The behavior of such an index will not change immediately unless you N)REINDEX it; otherwise space-stripped values will be gradually replaced over time during updates. Queries that do not use index-only scan plans will be unaffected in any case.
Change configure to use Python's sysconfig module, rather than the deprecated distutils module, to determine how to build PL/Python (Peter Eisentraut, Tom Lane, Andres Freund) §
\nWith Python 3.10, this avoids configure-time warnings about distutils being deprecated and scheduled for removal in Python 3.12. Presumably, once 3.12 is out, configure --with-python would fail altogether. This future-proofing does come at a cost: sysconfig did not exist before Python 2.7, nor before 3.2 in the Python 3 branch, so it is no longer possible to build PL/Python against long-dead Python versions.

\nHowever, note that installations using physical replication should update standby servers before the primary server, as explained in the third changelog entry below.
\nAlso, several bugs have been found that may have resulted in corrupted indexes, as explained in the next several changelog entries. If any of those cases apply to you, it's recommended to reindex possibly-affected indexes after updating.
\nAlso, if you are upgrading from a version earlier than 13.2, see Section E.22.

for the latest prepared transactions (Andrey Borodin) §
Rows inserted by just-prepared transactions might be omitted from the new index, causing queries relying on the index to miss such rows. The previous fix for this type of problem failed to account for PREPARE TRANSACTION commands that were still in progress when CREATE INDEX CONCURRENTLY checked for them. As before, in installations that have enabled prepared transactions (max_prepared_transactions > 0), it's recommended to reindex any concurrently-built indexes in case this problem occurred when they were built.
Avoid race condition that can cause backends to fail to add entries for new rows to an index being built concurrently (Noah Misch, Andrey Borodin) §
\nWhile it's apparently rare in the field, this case could potentially affect any index built or reindexed with the CONCURRENTLY option. It is recommended to reindex any such indexes to make sure they are correct.
Fix float4 and float8 hash functions to produce uniform results for NaNs (Tom Lane) § § §
Since PostgreSQL's floating-point types deem all NaNs to be equal, it's important for the hash functions to produce the same hash code for all bit-patterns that are NaNs according to the IEEE 754 standard. This failed to happen before, meaning that hash indexes and hash-based query plans might produce incorrect results for non-canonical NaN values. ('-NaN'::float8 is one way to produce such a value on most machines.) It is advisable to reindex hash indexes on floating-point columns, if there is any possibility that they might contain such values.
Fix REINDEX CONCURRENTLY to preserve operator class parameters that were attached to the target index (Michael Paquier) §
Prevent data loss during crash recovery of CREATE TABLESPACE, when wal_level = minimal (Noah Misch) §
If the server crashed between CREATE TABLESPACE and the next checkpoint, replay would fully remove the contents of the new tablespace's directory, relying on subsequent WAL replay to restore everything within that directory. This interacts badly with optimizations that skip writing WAL (one example is COPY into a just-created table). Such optimizations are applied only when wal_level is minimal, which is not the default in v10 and later.

\nFor example, if column f1 is of type numeric(18,3), the parser used to simply discard a cast like f1::numeric, on the grounds that it would have no run-time effect. That's true, but the exposed type of the expression should still be considered to be plain numeric, not numeric(18,3). This is important for correctly resolving the type of larger constructs, such as recursive UNIONs.
Fix updates of element fields in arrays of domain over composite (Tom Lane) §
\nA command such as UPDATE tab SET fld[1].subfld = val failed if the array's elements were domains rather than plain composites.
Disallow the combination of FETCH FIRST WITH TIES and FOR UPDATE SKIP LOCKED (David Christensen) §
FETCH FIRST WITH TIES necessarily fetches one more row than requested, since it cannot stop until it finds a row that is not a tie. In our current implementation, if FOR UPDATE is used then that row will also get locked even though it is not returned. That results in undesirable behavior if the SKIP LOCKED option is specified. It's difficult to change this without introducing a different set of undesirable behaviors, so for now, forbid the combination.

There's no infrastructure to support this, so if someone did it, it would only result in preventing cleanup of the NOTIFY queue.
Send NOTIFY signals to other backends during transaction commit, not in the server's idle loop (Artur Zakirov, Tom Lane) §
This change allows notifications to be delivered immediately after an intra-procedure COMMIT. It also allows logical replication workers to send notifications.
Refuse to rewind a cursor marked NO SCROLL if it has been held over from a previous transaction due to the WITH HOLD option (Tom Lane) §
We have long forbidden fetching backwards from a NO SCROLL cursor, but for historical reasons the prohibition didn't extend to cases in which we rewind the query altogether and then re-fetch forwards. That exception leads to inconsistencies, particularly for held-over cursors which may not have stored all the data necessary to rewind. Disallow rewinding for non-scrollable held-over cursors to block the worst inconsistencies. (v15 will remove the exception altogether.)
Fix possible failure while saving a WITH HOLD cursor at transaction end, if it had already been read to completion (Tom Lane) §

If the FILTER expression is a plain boolean column, the semantic level of the aggregate could be mis-determined, leading to not-per-spec behavior. If the FILTER expression is itself a boolean-returning aggregate, an error should be thrown but was not, likely resulting in a crash at execution.
Ensure that the correct lock level is used when renaming a table (Nathan Bossart, Álvaro Herrera) § §
\nFor historical reasons, ALTER INDEX ... RENAME can be applied to any sort of relation. The lock level required to rename an index is lower than that required to rename a table or other kind of relation, but the code got this wrong and would use the weaker lock level whenever the command is spelled ALTER INDEX.
Prevent ALTER TYPE/DOMAIN/OPERATOR ... SET from changing extension membership (Tom Lane) §
ALTER ... SET executed by an extension script would cause the target object to become a member of the extension if it was not already. In itself this isn't too troubling, since there's little reason for an extension script to touch an object not belonging to the extension. But ALTER TYPE SET will recurse to dependent domains, thus causing them to also become extension members. This causes unwanted side-effects from extension upgrade scripts that use that command to adjust the properties of a base type belonging to the extension. Fix by redefining these ALTER cases to never change extension membership.

Fix infinite loop if a simplehash.h hash table reaches 2^32 elements (Yura Sokolov) §
It seems unlikely that this bug has been hit in practice, as it would require work_mem settings of hundreds of gigabytes for existing uses of simplehash.h.
Avoid O(N^2) behavior in some list-manipulation operations (Nathan Bossart, Tom Lane) § § §
\nThese changes fix slow processing in several scenarios, including: when a standby replays a transaction that held many exclusive locks on the primary; when many files are due to be unlinked after a checkpoint; when hash aggregation involves many batches; and when pg_trgm extracts indexable conditions from a complex regular expression. Only the first of these scenarios has actually been reported from the field, but they all seem like plausible consequences of inefficient list deletions.

Remove pg_ctl's hard-coded limits on the total length of generated commands (Phil Krylov) §
\nFor example, this removes a restriction on how many command-line options can be passed through to the postmaster. Individual path names that pg_ctl deals with, such as the postmaster executable's name or the data directory name, are still limited to MAXPGPATH bytes in most cases.
Fix pg_dump to dump non-global default privileges correctly (Neil Chen, Masahiko Sawada) §
\nIf a global (unrestricted) ALTER DEFAULT PRIVILEGES command revoked some present-by-default privilege, for example EXECUTE for functions, and then a restricted ALTER DEFAULT PRIVILEGES command granted that privilege again for a selected role or schema, pg_dump failed to dump the restricted privilege grant correctly.

Make pg_regexec() robust against an out-of-range search_start parameter (Tom Lane) §
Return REG_NOMATCH, instead of possibly crashing, when search_start is past the end of the string. This case is probably unreachable within core PostgreSQL, but extensions might be more careless about the parameter value.
Ensure that GetSharedSecurityLabel() can be used in a newly-started session that has not yet built its critical relation cache entries (Jeff Davis) §
Use the CLDR project's data to map Windows time zone names to IANA time zones (Tom Lane) § § §
\nWhen running on Windows, initdb attempts to set the new cluster's timezone parameter to the IANA time zone matching the system's prevailing time zone. We were using a mapping table that we'd generated years ago and updated only fitfully; unsurprisingly, it contained a number of errors as well as omissions of recently-added zones. It turns out that CLDR has been tracking the most appropriate mappings, so start using their data. This change will not affect any existing installation, only newly-initialized clusters.
Update time zone data files to tzdata release 2021e for DST law changes in Fiji, Jordan, Palestine, and Samoa, plus historical corrections for Barbados, Cook Islands, Guyana, Niue, Portugal, and Tonga. (Tom Lane) §
\nAlso, the Pacific/Enderbury zone has been renamed to Pacific/Kanton. Also, the following zones have been merged into nearby, more-populous zones whose clocks have agreed with them since 1970: Africa/Accra, America/Atikokan, America/Blanc-Sablon, America/Creston, America/Curacao, America/Nassau, America/Port_of_Spain, Antarctica/DumontDUrville, and Antarctica/Syowa. In all these cases, the previous zone name remains as an alias.

Fix PREPARE TRANSACTION to check correctly for conflicting session-lifespan and transaction-lifespan locks (Tom Lane) §
A transaction cannot be prepared if it has both session-lifespan and transaction-lifespan locks on the same advisory-lock ID value. This restriction was not fully checked, which could lead to a PANIC during PREPARE TRANSACTION.

That's fairly harmless in the short run, but if new columns are added to the table then the values would become accessible, possibly leading to malfunctions if they don't match the datatypes of the added columns. In addition, in versions supporting cross-partition updates, a cross-partition update triggered by such a case had the reverse problem: the junk columns were removed from the target list, typically causing an immediate crash due to malfunction of the multi-column sub-select mechanism.

RETURNING outputs for joined cross-partition updates (Amit Langote, Etsuro Fujita) § §
If an UPDATE for a partitioned table caused a row to be moved to another partition with a physically different row type (for example, one with a different set of dropped columns), computation of RETURNING results for that row could produce errors or wrong answers. No error is observed unless the UPDATE involves other tables being joined to the target table. (CVE-2021-32029)
Fix adjustment of constraint deferrability properties in partitioned tables (Álvaro Herrera) §
\nWhen applied to a foreign-key constraint of a partitioned table, ALTER TABLE ... ALTER CONSTRAINT failed to adjust the DEFERRABLE and/or INITIALLY DEFERRED markings of the constraints and triggers of leaf partitions. This led to unexpected behavior of such constraints. After updating to this version, any misbehaving partitioned tables can be fixed by executing a new ALTER command to set the desired properties.
This change also disallows applying such an ALTER directly to the constraints of leaf partitions. The only supported case is for the whole partitioning hierarchy to have identical constraint properties, so such ALTERs must be applied at the partition root.

Disable the vacuum_cleanup_index_scale_factor parameter and storage option (Peter Geoghegan) § §
The notion of tracking “stale” index statistics proved to interact badly with the autovacuum_vacuum_insert_threshold parameter, resulting in unnecessary full-index scans and consequent degradation of autovacuum performance. The latter mechanism seems superior, so remove the stale-statistics logic. The control parameter for that, vacuum_cleanup_index_scale_factor, will be removed entirely in v14. In v13, it remains present to avoid breaking existing configuration files, but it no longer does anything.

When updating trigger properties during ALTER CONSTRAINT, the post-alter hook was told that we are updating a trigger, but the constraint's OID was passed instead of the trigger's.

This change ensures that permissions-related decisions will promptly reflect the results of ALTER ROLE ... [NO] INHERIT.
Fix failure to detect “snapshot too old” conditions in tables rewritten in the current transaction (Kyotaro Horiguchi, Noah Misch) §
\nThis is only a hazard when wal_level is set to minimal and the rewrite is performed by ALTER TABLE SET TABLESPACE.
Fix spurious failure of CREATE PUBLICATION when applied to a table created or rewritten in the current transaction (Kyotaro Horiguchi) §
This is only a hazard when wal_level is set to minimal.
Prevent misprocessing of ambiguous CREATE TABLE LIKE clauses (Tom Lane) §
A LIKE clause is re-examined after initial creation of the new table, to handle importation of indexes and such. It was possible for this re-examination to find a different table of the same name, causing unexpected behavior; one example is where the new table is a temporary table of the same name as the LIKE target.
Rearrange order of operations in CREATE TABLE LIKE so that indexes are cloned before building foreign key constraints (Tom Lane) §
This fixes the case where a self-referential foreign key constraint declared in the outer CREATE TABLE depends on an index that's coming from the LIKE clause.

\nRemove pointless restriction that only GSS authentication can be used on a GSS-encrypted connection. Add GSS encryption information to connection-authorized log messages. Include GSS-related space when computing the required size of shared memory (this omission could have caused problems with very high max_connections settings). Avoid possible infinite recursion when reporting an unrecoverable GSS encryption error.

In libpq, do not skip trying SSL after GSS encryption (Tom Lane) §
\nIf we successfully made a GSS-encrypted connection, but then failed during authentication, we would fall back to an unencrypted connection rather than next trying an SSL-encrypted connection. This could lead to unexpected connection failure, or to silently getting an unencrypted connection where an encrypted one is expected. Fortunately, GSS encryption could only succeed if both client and server hold valid tickets in the same Kerberos infrastructure.

Fix miscalculation of timeouts in contrib/pg_prewarm and contrib/postgres_fdw (Alexey Kondratov, Tom Lane) §
The main loop in contrib/pg_prewarm's autoprewarm parent process underestimated its desired sleep time by a factor of 1000, causing it to consume much more CPU than intended. When waiting for a result from a remote server, contrib/postgres_fdw overestimated the desired timeout by a factor of 1000 (though this error had been mitigated by imposing a clamp to 60 seconds).
Both of these errors stemmed from incorrectly converting seconds-and-microseconds to milliseconds. Introduce a new API TimestampDifferenceMilliseconds() to make it easier to get this right in the future.

\nThe -d parameter of pg_dump and pg_restore, or the --maintenance-db parameter of the other programs mentioned, can be a “connection string” containing multiple connection parameters rather than just a database name. In cases where these programs need to initiate additional connections, such as parallel processing or processing of multiple databases, the connection string was forgotten and just the basic connection parameters (database name, host, port, and username) were used for the additional connections. This could lead to connection failures if the connection string included any other essential information, such as non-default SSL or GSS parameters. Worse, the connection might succeed but not be encrypted as intended, or be vulnerable to man-in-the-middle attacks that the intended connection parameters would have prevented. (CVE-2020-25694)

In libpq for Windows, call WSAStartup() once per process and WSACleanup() not at all (Tom Lane, Alexander Lakhin) §
Previously, libpq invoked WSAStartup() at connection start and WSACleanup() at connection cleanup. However, it appears that calling WSACleanup() can interfere with other program operations; notably, we have observed rare failures to emit expected output to stdout. There appear to be no ill effects from omitting the call, so do that. (This also eliminates a performance issue from repeated DLL loads and unloads when a program performs a series of database connections.)
