Release 13.13
+
+
+
Release date:
+
+
+ This release contains a variety of fixes from 13.12.
+ For information about new features in major release 13, see
+ .
+
+
+
+
Migration to Version 13.13
+
+ A dump/restore is not required for those running 13.X.
+
+
+ However, several mistakes have been discovered that could lead to
+ certain types of indexes yielding wrong search results.
+ It is advisable
+ to REINDEX potentially-affected indexes after
+ installing this update. See the first and second changelog
+ entries below.
+
+
+ Also, if you are upgrading from a version earlier than 13.12,
+ see .

Changes
+
+
+
+
+
+ Fix misbehavior during recursive page split in GiST index build
+ (Heikki Linnakangas)
+
+
+ Fix a case where the location of a page downlink was incorrectly
+ tracked, and introduce some logic to allow recovering from such
+ situations rather than silently doing the wrong thing. This error
+ could result in incorrect answers from subsequent index searches.
+ It may be advisable to reindex all GiST indexes after installing
+ this update.
+
+
+
+
+
+ Prevent de-duplication of btree index entries
+ for interval columns (Noah Misch)
+
+
+ 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)
+
+
+ Some 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)
+
+
+ When 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.
+
+
+
+
+
+ Fix intra-query memory leak when a set-returning function repeatedly
+ returns zero rows (Tom Lane)
+
+
+
+
+
+ Don't crash if cursor_to_xmlschema() is applied
+ to a non-data-returning Portal (Boyu Yang)
+
+
+
+
+
+ Throw the intended error if pgrowlocks() is
+ applied to a partitioned table (David Rowley)
+
+
+ Previously, a not-on-point complaint only heap AM is
+ supported would be raised.
+
+
+
+
+
+ Handle invalid indexes more cleanly in assorted SQL functions
+ (Noah Misch)
+
+
+ Report 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.
+
+
+
+
+
+ Improve checks for corrupt PGLZ compressed data (Flavien Guedez)
+
+
+
+
+
+ Fix COMMIT AND CHAIN/ROLLBACK AND
+ CHAIN to work properly when there is an unreleased
+ savepoint (Liu Xiang, Tom Lane)
+
+
+ Instead of propagating the current transaction's properties to the
+ new transaction, they propagated some previous transaction's
+ properties.
+
+
+
+
+
+ Avoid crash in EXPLAIN if a parameter marked to
+ be displayed by EXPLAIN has a NULL boot-time
+ value (Xing Guo, Aleksander Alekseev, Tom Lane)
+
+
+ No built-in parameter fits this description, but an extension could
+ define such a parameter.
+
+
+
+
+
+ Ensure we have a snapshot while dropping ON COMMIT
+ DROP temp tables (Tom Lane)
+
+
+ This prevents possible misbehavior if any catalog entries for the
+ temp tables have fields wide enough to require toasting (such as a
+ very complex CHECK condition).
+
+
+
+
+
+ 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)
+
+
+ On 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.
+
+
+
+
+
+ Fix briefly showing inconsistent progress statistics
+ for ANALYZE on inherited tables
+ (Heikki Linnakangas)
+
+
+ The block-level counters should be reset to zero at the same time we
+ update the current-relation field.
+
+
+
+
+
+ Track the dependencies of cached CALL statements,
+ and re-plan them when needed (Tom Lane)
+
+
+ DDL commands, such as replacement of a function that has been
+ inlined into a CALL argument, can create the need
+ to re-plan a CALL that has been cached by
+ PL/pgSQL. That was not happening, leading to misbehavior or strange
+ errors such as cache lookup failed
.
+
+
+
+
+
+ Track nesting depth correctly when
+ inspecting RECORD-type Vars from outer query levels
+ (Richard Guo)
+
+
+ This oversight could lead to assertion failures, core dumps,
+ or bogus varno
errors.
+
+
+
+
+
+ Avoid record type has not been registered
failure
+ when deparsing a view that contains references to fields of
+ composite constants (Tom Lane)
+
+
+
+
+
+ Fix error-handling bug in RECORD type cache management
+ (Thomas Munro)
+
+
+ An out-of-memory error occurring at just the wrong point could leave
+ behind inconsistent state that would lead to an infinite loop.
+
+
+
+
+
+ Fix assertion failure when logical decoding is retried in the same
+ session after an error (Hou Zhijie)
+
+
+
+
+
+ Treat out-of-memory failures as fatal while reading WAL
+ (Michael Paquier)
+
+
+ Previously this would be treated as a bogus-data condition, leading
+ to the conclusion that we'd reached the end of WAL, which is
+ incorrect and could lead to inconsistent WAL replay.
+
+
+
+
+
+ Fix possible recovery failure due to trying to allocate memory based
+ on a bogus WAL record length field (Thomas Munro, Michael Paquier)
+
+
+
+
+
+ Ensure that standby-mode WAL recovery reports an error when an
+ invalid page header is found (Yugo Nagata, Kyotaro Horiguchi)
+
+
+
+
+
+ Fix datatype size confusion in logical tape management
+ (Ranier Vilela)
+
+
+ Integer overflow was possible on platforms where long is wider than
+ int, although it would take a multiple-terabyte temporary file to
+ cause a problem.
+
+
+
+
+
+ Avoid unintended close of syslogger process's stdin
+ (Heikki Linnakangas)
+
+
+
+
+
+ Avoid doing plan cache revalidation of utility statements
+ that do not receive interesting processing during parse analysis
+ (Tom Lane)
+
+
+ Aside from saving a few cycles, this prevents failure after a cache
+ invalidation for statements that must not set a snapshot, such
+ as SET TRANSACTION ISOLATION LEVEL.
+
+
+
+
+
+ Keep by-reference attmissingval values in
+ a long-lived context while they are being used (Andrew Dunstan)
+
+
+ This avoids possible use of dangling pointers when a tuple slot
+ outlives the tuple descriptor with which its value was constructed.
+
+
+
+
+
+ Recalculate the effective value of search_path
+ after ALTER ROLE (Jeff Davis)
+
+
+ This ensures that after renaming a role, the meaning of the special
+ string $user is re-determined.
+
+
+
+
+
+ Fix order of operations in GenericXLogFinish
+ (Jeff Davis)
+
+
+ This code violated the conditions required for crash safety by
+ writing WAL before marking changed buffers dirty. No core code uses
+ this function, but extensions do (contrib/bloom
+ does, for example).
+
+
+
+
+
+ Remove incorrect assertion in PL/Python exception handling
+ (Alexander Lakhin)
+
+
+
+
+
+ Fix
pg_restore so that selective restores
+ will include both table-level and column-level ACLs for selected
+ tables (Euler Taveira, Tom Lane)
+
+
+ Formerly, only the table-level ACL would get restored if both types
+ were present.
+
+
+
+
+
+ Add logic to
pg_upgrade to check for use
+ of abstime, reltime,
+ and tinterval data types (Álvaro Herrera)
+
+
+ These obsolete data types were removed
+ in
PostgreSQL version 12, so check to
+ make sure they aren't present in an older database before claiming
+ it can be upgraded.
+
+
+
+
+
+ Avoid generating invalid temporary slot names
+ in
pg_basebackup (Jelte Fennema)
+
+
+ This has only been seen to occur when the server connection runs
+
+
+
+
+
+ Avoid false too many client connections
errors
+ in
pgbench on Windows (Noah Misch)
+
+
+
+
+
+ In contrib/amcheck, do not report interrupted
+ page deletion as corruption (Noah Misch)
+
+
+ This fix prevents false-positive reports of the first child
+ of leftmost target page is not leftmost of its
+ level, block NNNN is not leftmost
+ or left link/right link pair in index XXXX not in
+ agreement. They appeared
+ if
amcheck ran after an unfinished btree
+ index page deletion and before VACUUM had cleaned
+ things up.
+
+
+
+
+
+ Fix failure of contrib/btree_gin indexes
+ on interval columns,
+ when an indexscan using the <
+ or <= operator is performed (Dean Rasheed)
+
+
+ Such an indexscan failed to return all the entries it should.
+
+
+
+
+
+ Add support for LLVM 16 and 17 (Thomas Munro, Dmitry Dolgov)
+
+
+
+
+
+ Suppress assorted build-time warnings on
+ recent
macOS (Tom Lane)
+
+
+ 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
+ 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. If someone does,
+ they can put it back via a custom abbreviations file.
