\nThe 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).
\nBoth 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.

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.)

That will provide about the same performance as before, and it will find all non-empty subsets of the given constant array, which is all that could reliably be expected of the query before.", "commit_aliases": ["113b3d903", "2f76f4182", "5b3e6c13f", "614119d00", "ced272d2d", "e519eded6", "efc77cf5f"], "source_commits": ["ced272d2d"], "source_entry_id": "9.5.20/changes/043", "db_id": "1c9f43f55f1b5b56c782ba572b576692", "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e", "relations": [{"rule": 2, "type": "equivalent", "target": "095d1b932d2c8b19ac2c80541fa441c9", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "3aca8549b51328708bd5a5bf23277edc", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "73e885c18b9f26670dcde44f3cce58b1", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "85ba616e74f33ab854bbdba4c2efb25a", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}], "version": "9.5.20", "category_label": "Bug fixes", "also_in": [], "variants": [], "related_changes": [{"db_id": "3aca8549b51328708bd5a5bf23277edc", "kind": "equivalent", "version": "11.6", "label": "11.6", "title": "Fix contrib/intarray's GiST opclasses to not fail for empty arrays with <@", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=11.6#11.6-3f122217ad9dcf0d", "source_url": "/docs/release/11.6/#id-1.11.6.21.5"}, {"db_id": "095d1b932d2c8b19ac2c80541fa441c9", "kind": "equivalent", "version": "10.11", "label": "10.11", "title": "Fix contrib/intarray's GiST opclasses to not fail for empty arrays with <@", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=10.11#10.11-3f122217ad9dcf0d", "source_url": "/docs/release/10.11/#id-1.11.6.17.5"}, {"db_id": "73e885c18b9f26670dcde44f3cce58b1", "kind": "equivalent", "version": "9.6.16", "label": "9.6.16", "title": "Fix contrib/intarray's GiST opclasses to not fail for empty arrays with <@", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.6.16#9.6.16-3f122217ad9dcf0d", "source_url": "/docs/release/9.6.16/#AEN133252"}, {"db_id": "85ba616e74f33ab854bbdba4c2efb25a", "kind": "equivalent", "version": "9.4.25", "label": "9.4.25", "title": "Fix contrib/intarray's GiST opclasses to not fail for empty arrays with <@", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.4.25#9.4.25-3f122217ad9dcf0d", "source_url": "/docs/release/9.4.25/#AEN119951"}]}, {"id": "9.5.20-ddabe02d733cbe5a", "cves": [], "html": "Allow configure --with-python to succeed when only python3 or only python2 can be found (Peter Eisentraut, Tom Lane)

\nUp to now, we've forbidden datatype-specific comparison functions from returning INT_MIN, which allows callers to invert the sort order just by negating the comparison result. However, this was never safe for comparison functions that directly return the result of memcmp(), strcmp(), etc, as POSIX doesn't place any such restriction on those functions. At least some recent versions of memcmp() can return INT_MIN, causing incorrect sort ordering. Hence, we've removed this restriction. Callers must now use the INVERT_COMPARE_RESULT() macro if they wish to invert the sort order.
Fix recursion hazard in shared-invalidation message processing (Tom Lane)
\nThis error could, for example, result in failure to access a system catalog or index that had just been processed by VACUUM FULL.
\nThis change adds a new result code for LockAcquire, which might possibly affect external callers of that function, though only very unusual usage patterns would have an issue with it. The API of LockAcquireExtended is also changed.

This does not affect either the actual UTC offset or the timezone abbreviations in use; the only known effect is that the is_dst column in the pg_timezone_names view will now be true in winter and false in summer in these cases.", "commit_aliases": [], "source_commits": [], "source_entry_id": "9.5.14/changes/030", "db_id": "4665643582ca528c025ca51ef876640b", "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c", "relations": [{"rule": 2, "type": "equivalent", "target": "5e2e95399fa99faba1ec919a703975de", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}}, {"rule": 2, "type": "equivalent", "target": "e66a4e42e0632f51b3db77194fc6ea05", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}}, {"rule": 2, "type": "equivalent", "target": "eab8b499ede5f2e4cd22b4228850bace", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}}, {"rule": 2, "type": "equivalent", "target": "eae244a6dda158da8e88045e274b818f", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}}], "version": "9.5.14", "category_label": "Improvements", "also_in": [], "variants": [], "related_changes": [{"db_id": "e66a4e42e0632f51b3db77194fc6ea05", "kind": "equivalent", "version": "10.5", "label": "10.5", "title": "Update time zone data files to tzdata release 2018e for DST law changes in North Korea, plus historical corrections for Czechoslovakia.", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}, "url": "/docs/compare/?release=10.5#10.5-d9e7fdabc8642516", "source_url": "/docs/release/10.5/#id-1.11.6.23.5"}, {"db_id": "eae244a6dda158da8e88045e274b818f", "kind": "equivalent", "version": "9.6.10", "label": "9.6.10", "title": "Update time zone data files to tzdata release 2018e for DST law changes in North Korea, plus historical corrections for Czechoslovakia.", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}, "url": "/docs/compare/?release=9.6.10#9.6.10-d9e7fdabc8642516", "source_url": "/docs/release/9.6.10/#AEN134332"}, {"db_id": "eab8b499ede5f2e4cd22b4228850bace", "kind": "equivalent", "version": "9.4.19", "label": "9.4.19", "title": "Update time zone data files to tzdata release 2018e for DST law changes in North Korea, plus historical corrections for Czechoslovakia.", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}, "url": "/docs/compare/?release=9.4.19#9.4.19-d9e7fdabc8642516", "source_url": "/docs/release/9.4.19/#AEN120815"}, {"db_id": "5e2e95399fa99faba1ec919a703975de", "kind": "equivalent", "version": "9.3.24", "label": "9.3.24", "title": "Update time zone data files to tzdata release 2018e for DST law changes in North Korea, plus historical corrections for Czechoslovakia.", "evidence": {"same_day": true, "patch_ids": [], "statement_hash": "121e90e8bc23ffc5b72b1b0813a32d1c613b718c6334e0d052ff766689a0a87c"}, "url": "/docs/compare/?release=9.3.24#9.3.24-d9e7fdabc8642516", "source_url": "/docs/release/9.3.24/#AEN115312"}]}]}, {"date": "2018-05-10", "build": "9.5.13", "major": "9.5", "minor": 13, "manual": "9.5", "status": "stable", "doc_git": "", "version": "9.5.13", "eol_date": "2021-02-11", "date_text": "2018-05-10", "supported": false, "manual_url": "/docs/9.5/release-9-5-13.html", "source_url": "/docs/release/9.5.13/", "entry_count": 38, "placeholder": false, "content_hash": "323bb5a377ae7d5c9904fe3b5893040e6f37759b56916d2f7a76fada296f91cd", "manual_build": "9.5.25", "source_as_of": "", "changes_count": 38, "doc_loaded_at": "2026-09-25T02:22:44.760693", "migration_html": "A dump/restore is not required for those running 9.5.X.

\nThe functions query_to_xml, cursor_to_xml, cursor_to_xmlschema, query_to_xmlschema, and query_to_xml_and_xmlschema should be marked volatile because they execute user-supplied queries that might contain volatile operations. They were not, leading to a risk of incorrect query optimization. This has been repaired for new installations by correcting the initial catalog data, but existing installations will continue to contain the incorrect markings. Practical use of these functions seems to pose little hazard, but in case of trouble, it can be fixed by manually updating these functions' pg_proc entries, for example ALTER FUNCTION pg_catalog.query_to_xml(text, boolean, boolean, text) VOLATILE. (Note that that will need to be done in each database of the installation.) Another option is to pg_upgrade the database to a version containing the corrected initial data.
Avoid re-using TOAST value OIDs that match dead-but-not-yet-vacuumed TOAST entries (Pavan Deolasee)
\nOnce the OID counter has wrapped around, it's possible to assign a TOAST value whose OID matches a previously deleted entry in the same TOAST table. If that entry were not yet vacuumed away, this resulted in \"unexpected chunk number 0 (expected 1) for toast value nnnnn\" errors, which would persist until the dead entry was removed by VACUUM. Fix by not selecting such OIDs when creating a new TOAST entry.

In databases using UTF8 encoding, ignore any XML declaration that asserts a different encoding (Pavel Stehule, Noah Misch)
\nWe always store XML strings in the database encoding, so allowing libxml to act on a declaration of another encoding gave wrong results. In encodings other than UTF8, we don't promise to support non-ASCII XML data anyway, so retain the previous behavior for bug compatibility.

\nUp to now, PostgreSQL servers simply rejected requests to use protocol versions newer than 3.0, so that there was no functional difference between the major and minor parts of the protocol version number. Allow clients to request versions 3.x without failing, sending back a message showing that the server only understands 3.0. This makes no difference at the moment, but back-patching this change should allow speedier introduction of future minor protocol upgrades.

\nThe fix for CVE-2017-7486 was incorrect: it allowed a user to see the options in her own user mapping, even if she did not have USAGE permission on the associated foreign server. Such options might include a password that had been provided by the server owner rather than the user herself. Since information_schema.user_mapping_options does not show the options in such cases, pg_user_mappings should not either. (CVE-2017-7547)
\nBy itself, this patch will only fix the behavior in newly initdb'd databases. If you wish to apply this change in an existing database, you will need to do the following:
\nRestart the postmaster after adding allow_system_table_mods = true to postgresql.conf. (In versions supporting ALTER SYSTEM, you can use that to make the configuration change, but you'll still need a restart.)
\nIn each database of the cluster, run the following commands as superuser:
\nSET search_path = pg_catalog;\nCREATE OR REPLACE VIEW pg_user_mappings AS\n SELECT\n U.oid AS umid,\n S.oid AS srvid,\n S.srvname AS srvname,\n U.umuser AS umuser,\n CASE WHEN U.umuser = 0 THEN\n 'public'\n ELSE\n A.rolname\n END AS usename,\n CASE WHEN (U.umuser <> 0 AND A.rolname = current_user\n AND (pg_has_role(S.srvowner, 'USAGE')\n OR has_server_privilege(S.oid, 'USAGE')))\n OR (U.umuser = 0 AND pg_has_role(S.srvowner, 'USAGE'))\n OR (SELECT rolsuper FROM pg_authid WHERE rolname = current_user)\n THEN U.umoptions\n ELSE NULL END AS umoptions\n FROM pg_user_mapping U\n LEFT JOIN pg_authid A ON (A.oid = U.umuser) JOIN\n pg_foreign_server S ON (U.umserver = S.oid);\n
Do not forget to include the template0 and template1 databases, or the vulnerability will still exist in databases you create later. To fix template0, you'll need to temporarily make it accept connections. In PostgreSQL 9.5 and later, you can use
\nALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n\n
and then after fixing template0, undo that with
\nALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n\n
In prior versions, instead use
\nUPDATE pg_database SET datallowconn = true WHERE datname = 'template0';\nUPDATE pg_database SET datallowconn = false WHERE datname = 'template0';\n
Finally, remove the allow_system_table_mods configuration setting, and again restart the postmaster.
\nDisallow empty passwords in all password-based authentication methods (Heikki Linnakangas)
\nlibpq ignores empty password specifications, and does not transmit them to the server. So, if a user's password has been set to the empty string, it's impossible to log in with that password via psql or other libpq-based clients. An administrator might therefore believe that setting the password to empty is equivalent to disabling password login. However, with a modified or non-libpq-based client, logging in could be possible, depending on which authentication method is configured. In particular the most common method, md5, accepted empty passwords. Change the server to reject empty passwords in all cases. (CVE-2017-7546)
