Release history

Every indexed release keeps its original occurrences. CVE counts below are mentions in its notes, including follow-up corrections; they do not count newly fixed vulnerabilities.

Initial release changes

Original entries from 9.5.0, including feature changes and compatibility notes. Categories aid browsing; they are not upstream classifications.

193 of 193 original entries.

• Adjust operator precedence to match the SQL standard Compatibility Migration

  Adjust operator precedence to match the SQL standard (Tom Lane)

  The precedence of <=, >= and <> has been reduced to match that of <, > and =. The precedence of IS tests (e.g., x IS NULL) has been reduced to be just below these six comparison operators. Also, multi-keyword operators beginning with NOT now have the precedence of their base operator (for example, NOT BETWEEN now has the same precedence as BETWEEN) whereas before they had inconsistent precedence, behaving like NOT with respect to their left operand but like their base operator with respect to their right operand. The new configuration parameter operator_precedence_warning can be enabled to warn about queries in which these precedence changes result in different parsing choices.

  Original release occurrence · 9.5.0/migration/001

• Change pg_ctl's default shutdown mode from smart to fast Compatibility Migration

  Change pg_ctl's default shutdown mode from smart to fast (Bruce Momjian)

  This means the default behavior will be to forcibly cancel existing database sessions, not simply wait for them to exit.

  Original release occurrence · 9.5.0/migration/002

• Use assignment cast behavior for data type conversions in PL/pgSQL assignments, rather than converting to and from text Compatibility Migration

  Use assignment cast behavior for data type conversions in PL/pgSQL assignments, rather than converting to and from text (Tom Lane)

  This change causes conversions of Booleans to strings to produce true or false, not t or f. Other type conversions may succeed in more cases than before; for example, assigning a numeric value 3.9 to an integer variable will now assign 4 rather than failing. If no assignment-grade cast is defined for the particular source and destination types, PL/pgSQL will fall back to its old I/O conversion behavior.

  Original release occurrence · 9.5.0/migration/003

• Allow characters in server command-line options to be escaped with a backslash Compatibility Migration

  Allow characters in server command-line options to be escaped with a backslash (Andres Freund)

  Formerly, spaces in the options string always separated options, so there was no way to include a space in an option value. Including a backslash in an option value now requires writing \\.

  Original release occurrence · 9.5.0/migration/004

• Change the default value of the GSSAPI include_realm parameter to 1, so that by default the realm is not removed from a GSS or SSPI principal name Compatibility Migration

  Change the default value of the GSSAPI include_realm parameter to 1, so that by default the realm is not removed from a GSS or SSPI principal name (Stephen Frost)

  Original release occurrence · 9.5.0/migration/005

• Replace configuration parameter checkpoint_segments with min_wal_size and max_wal_size Compatibility Migration

  Replace configuration parameter checkpoint_segments with min_wal_size and max_wal_size (Heikki Linnakangas)

  If you previously adjusted checkpoint_segments, the following formula will give you an approximately equivalent setting:

  max_wal_size = (3 * checkpoint_segments) * 16MB
  

  Note that the default setting for max_wal_size is much higher than the default checkpoint_segments used to be, so adjusting it might no longer be necessary.

  Original release occurrence · 9.5.0/migration/006

• Control the Linux OOM killer via new environment variables PG_OOM_ADJUST_FILE and PG_OOM_ADJUST_VALUE, instead of compile-time options LINUX_OOM_SCORE_ADJ and LINUX_OOM_ADJ Compatibility Migration

  Control the Linux OOM killer via new environment variables PG_OOM_ADJUST_FILE and PG_OOM_ADJUST_VALUE, instead of compile-time options LINUX_OOM_SCORE_ADJ and LINUX_OOM_ADJ (Gurjeet Singh)

  Original release occurrence · 9.5.0/migration/007

• Decommission server configuration parameter ssl_renegotiation_limit, which was deprecated in earlier releases Compatibility Migration

  Decommission server configuration parameter ssl_renegotiation_limit, which was deprecated in earlier releases (Andres Freund)

  While SSL renegotiation is a good idea in theory, it has caused enough bugs to be considered a net negative in practice, and it is due to be removed from future versions of the relevant standards. We have therefore removed support for it from PostgreSQL. The ssl_renegotiation_limit parameter still exists, but cannot be set to anything but zero (disabled). It's not documented anymore, either.

  Original release occurrence · 9.5.0/migration/008

• Remove server configuration parameter autocommit, which was already deprecated and non-operational Compatibility Migration

  Remove server configuration parameter autocommit, which was already deprecated and non-operational (Tom Lane)

  Original release occurrence · 9.5.0/migration/009

• Remove the pg_authid catalog's rolcatupdate field, as it had no usefulness Compatibility Migration

  Remove the pg_authid catalog's rolcatupdate field, as it had no usefulness (Adam Brightwell)

  Original release occurrence · 9.5.0/migration/010

• The pg_stat_replication system view's sent field is now NULL, not zero, when it has no valid value Compatibility Migration

  The pg_stat_replication system view's sent field is now NULL, not zero, when it has no valid value (Magnus Hagander)

  Original release occurrence · 9.5.0/migration/011

• Allow json and jsonb array extraction operators to accept negative subscripts, which count from the end of JSON arrays Compatibility Migration

  Allow json and jsonb array extraction operators to accept negative subscripts, which count from the end of JSON arrays (Peter Geoghegan, Andrew Dunstan)

  Previously, these operators returned NULL for negative subscripts.

  Original release occurrence · 9.5.0/migration/012

• Add Block Range Indexes (BRIN) Features

  Add Block Range Indexes (BRIN) (Álvaro Herrera)

  BRIN indexes store only summary data (such as minimum and maximum values) for ranges of heap blocks. They are therefore very compact and cheap to update; but if the data is naturally clustered, they can still provide substantial speedup of searches.

  Original release occurrence · 9.5.0/changes/001

• Allow queries to perform accurate distance filtering of bounding-box-indexed objects (polygons, circles) using GiST indexes Features

  Allow queries to perform accurate distance filtering of bounding-box-indexed objects (polygons, circles) using GiST indexes (Alexander Korotkov, Heikki Linnakangas)

  Previously, to exploit such an index a subquery had to be used to select a large number of rows ordered by bounding-box distance, and the result then had to be filtered further with a more accurate distance calculation.

  Original release occurrence · 9.5.0/changes/002

• Allow GiST indexes to perform index-only scans Features

  Allow GiST indexes to perform index-only scans (Anastasia Lubennikova, Heikki Linnakangas, Andreas Karlsson)

  Original release occurrence · 9.5.0/changes/003

• Add configuration parameter gin_pending_list_limit to control the size of GIN pending lists Features

  Add configuration parameter gin_pending_list_limit to control the size of GIN pending lists (Fujii Masao)

  This value can also be set on a per-index basis as an index storage parameter. Previously the pending-list size was controlled by work_mem, which was awkward because appropriate values for work_mem are often much too large for this purpose.

  Original release occurrence · 9.5.0/changes/004

  Original release occurrence · 9.5.0/changes/028

• Replace configuration parameter checkpoint_segments with min_wal_size and max_wal_size Features

  Replace configuration parameter checkpoint_segments with min_wal_size and max_wal_size (Heikki Linnakangas)

  This change allows the allocation of a large number of WAL files without keeping them after they are no longer needed. Therefore the default for max_wal_size has been set to 1GB, much larger than the old default for checkpoint_segments. Also note that standby servers perform restartpoints to try to limit their WAL space consumption to max_wal_size; previously they did not pay any attention to checkpoint_segments.
