+ Release 10.6
+
+
+ Release date:
+ 2018-11-08
+
+
+
+ This release contains a variety of fixes from 10.5.
+ For information about new features in major release 10, see

+
+
+
+ Migration to Version 10.6
+
+
+ A dump/restore is not required for those running 10.X.

+
+ However, if you use the pg_stat_statements extension,
+ see the changelog entry below about that.
+
+
+
+ Also, if you are upgrading from a version earlier than 10.4,

+
+
+
+
+ Changes
+
+
+
+
+
+
+ Fix corner-case failures
+ in has_foo_privilege()
+ family of functions (Tom Lane)
+
+
+
+ Return NULL rather than throwing an error when an invalid object OID
+ is provided. Some of these functions got that right already, but not
+ all. has_column_privilege() was additionally
+ capable of crashing on some platforms.
+
+
+
+
+
+
+ Fix pg_get_partition_constraintdef() to return
+ NULL rather than fail when passed an invalid relation OID (Tom Lane)
+
+
+
+
+
+
+ Avoid O(N^2) slowdown in regular expression match/split functions on
+ long strings (Andrew Gierth)
+
+
+
+
+
+
+ Fix parsing of standard multi-character operators that are immediately
+ followed by a comment or + or -
+ (Andrew Gierth)
+
+
+
+ This oversight could lead to parse errors, or to incorrect assignment
+ of precedence.
+
+
+
+
+
+
+ Avoid O(N^3) slowdown in lexer for long strings
+ of + or - characters
+ (Andrew Gierth)
+
+
+
+
+
+
+ Fix mis-execution of SubPlans when the outer query is being scanned
+ backwards (Andrew Gierth)
+
+
+
+
+
+
+ Fix failure of UPDATE/DELETE ... WHERE CURRENT OF ...
+ after rewinding the referenced cursor (Tom Lane)
+
+
+
+ A cursor that scans multiple relations (particularly an inheritance
+ tree) could produce wrong behavior if rewound to an earlier relation.
+
+
+
+
+
+
+ Fix EvalPlanQual to handle conditionally-executed
+ InitPlans properly (Andrew Gierth, Tom Lane)
+
+
+
+ This resulted in hard-to-reproduce crashes or wrong answers in
+ concurrent updates, if they contained code such as an uncorrelated
+ sub-SELECT inside a CASE
+ construct.
+
+
+
+
+
+ Fix character-class checks to not fail on Windows for Unicode
+ characters above U+FFFF (Tom Lane, Kenji Uno)
+
+
+
+ This bug affected full-text-search operations, as well
+ as contrib/ltree
+ and contrib/pg_trgm.
+
+
+
+
+
+
+ Disallow pushing sub-SELECTs containing window
+ functions, LIMIT, or OFFSET to
+ parallel workers (Amit Kapila)
+
+
+
+ Such cases could result in inconsistent behavior due to different
+ workers getting different answers, as a result of indeterminacy
+ due to row-ordering variations.
+
+
+
+
+
+
+ Ensure that sequences owned by a foreign table are processed
+ by ALTER OWNER on the table (Peter Eisentraut)
+
+
+
+ The ownership change should propagate to such sequences as well, but
+ this was missed for foreign tables.
+
+
+
+
+
+ Ensure that the server will process
+ already-received NOTIFY
+ and SIGTERM interrupts before waiting for client
+ input (Jeff Janes, Tom Lane)
+
+
+
+
+
+
+ Fix over-allocation of space for array_out()'s
+ result string (Keiichi Hirobe)
+
+
+
+
+
+
+ Avoid query-lifetime memory leak in XMLTABLE
+ (Andrew Gierth)
+
+
+
+
+
+ Fix memory leak in repeated SP-GiST index scans (Tom Lane)
+
+
+
+ This is only known to amount to anything significant in cases where
+ an exclusion constraint using SP-GiST receives many new index entries
+ in a single command.
+
+
+
+
+
+
+ Ensure that ApplyLogicalMappingFile() closes the
+ mapping file when done with it (Tomas Vondra)
+
+
+
+ Previously, the file descriptor was leaked, eventually resulting in
+ failures during logical decoding.
+
+
+
+
+
+
+ Fix logical decoding to handle cases where a mapped catalog table is
+ repeatedly rewritten, e.g. by VACUUM FULL
+ (Andres Freund)
+
+
+
+
+
+ Prevent starting the server with wal_level set
+ to too low a value to support an existing replication slot (Andres
+ Freund)
+
+
+
+
+
+
+ Avoid crash if a utility command causes infinite recursion (Tom Lane)
+
+
+
+
+
+
+ When initializing a hot standby, cope with duplicate XIDs caused by
+ two-phase transactions on the master
+ (Michael Paquier, Konstantin Knizhnik)
+
+
+
+
+
+
+ Fix event triggers to handle nested ALTER TABLE
+ commands (Michael Paquier, Álvaro Herrera)
+
+
+
+
+
+
+ Propagate parent process's transaction and statement start timestamps
+ to parallel workers (Konstantin Knizhnik)
+
+
+
+ This prevents misbehavior of functions such
+ as transaction_timestamp() when executed in a
+ worker.
+
+
+
+
+
+
+ Fix transfer of expanded datums to parallel workers so that alignment
+ is preserved, preventing crashes on alignment-picky platforms
+ (Tom Lane, Amit Kapila)
+
+
+
+
+
+
+ Fix WAL file recycling logic to work correctly on standby servers
+ (Michael Paquier)
+
+
+
+ Depending on the setting of archive_mode, a standby
+ might fail to remove some WAL files that could be removed.
+
+
+
+
+
+
+ Fix handling of commit-timestamp tracking during recovery
+ (Masahiko Sawasa, Michael Paquier)
+
+
+
+ If commit timestamp tracking has been turned on or off, recovery might
+ fail due to trying to fetch the commit timestamp for a transaction
+ that did not record it.
+
+
+
+
+
+
+ Randomize the random() seed in bootstrap and
+ standalone backends, and in initdb
+ (Noah Misch)
+
+
+
+ The main practical effect of this change is that it avoids a scenario
+ where initdb might mistakenly conclude that
+ POSIX shared memory is not available, due to name collisions caused by
+ always using the same random seed.
+
+
+
+
+
+
+ Fix possible shared-memory corruption in DSA logic (Thomas Munro)
+
+
+
+
+
+
+ Allow DSM allocation to be interrupted (Chris Travers)
+
+
+
+
+
+
+ Avoid failure in a parallel worker when loading an extension that
+ tries to access system caches within its init function (Thomas Munro)
+
+
+
+ We don't consider that to be good extension coding practice, but it
+ mostly worked before parallel query, so continue to support it for
+ now.
+
+
+
+
+
+
+ Properly handle turning full_page_writes on
+ dynamically (Kyotaro Horiguchi)
+
+
+
+
+
+
+ Fix possible crash due to double free() during
+ SP-GiST rescan (Andrew Gierth)
+
+
+
+
+
+
+ Prevent mis-linking of src/port and src/common functions on ELF-based
+ BSD platforms, as well as HP-UX and Solaris (Andrew Gierth, Tom Lane)
+
+
+
+ Shared libraries loaded into a backend's address space could use the
+ backend's versions of these functions, rather than their own copies as
+ intended. Since the behavior of the two sets of functions isn't
+ quite the same, this led to failures.
+
+
+
+
+
+
+ Avoid possible buffer overrun when replaying GIN page recompression
+ from WAL (Alexander Korotkov, Sivasubramanian Ramasubramanian)
+
+
+
+
+
+
+ Avoid overrun of a hash index's metapage
+ when BLCKSZ is smaller than default (Dilip Kumar)
+
+
+
+
+
+
+ Fix missed page checksum updates in hash indexes (Amit Kapila)
+
+
+
+
+
+
+ Fix missed fsync of a replication slot's directory (Konstantin
+ Knizhnik, Michael Paquier)
+
+
+
+
+
+
+ Fix unexpected timeouts when
+ using wal_sender_timeout on a slow server
+ (Noah Misch)
+
+
+
+
+
+
+ Ensure that hot standby processes use the correct WAL consistency
+ point (Alexander Kukushkin, Michael Paquier)
+
+
+
+ This prevents possible misbehavior just after a standby server has
+ reached a consistent database state during WAL replay.
+
+
+
+
+
+
+ Ensure background workers are stopped properly when the postmaster
+ receives a fast-shutdown request before completing database startup
+ (Alexander Kukushkin)
+
+
+
+
+
+
+ Update the free space map during WAL replay of page all-visible/frozen
+ flag changes (Álvaro Herrera)
+
+
+
+ Previously we were not careful about this, reasoning that the FSM is
+ not critical data anyway. However, if it's sufficiently out of date,
+ that can result in significant performance degradation after a standby
+ has been promoted to primary. The FSM will eventually be healed by
+ updates, but we'd like it to be good sooner, so work harder at
+ maintaining it during WAL replay.
+
+
+
+
+
+
+ Avoid premature release of parallel-query resources when query end or
+ tuple count limit is reached (Amit Kapila)
+
+
+
+ It's only okay to shut down the executor at this point if the caller
+ cannot demand backwards scan afterwards.
+
+
+
+
+
+
+ Don't run atexit callbacks when servicing SIGQUIT
+ (Heikki Linnakangas)
+
+
+
+
+
+
+ Don't record foreign-server user mappings as members of extensions
+ (Tom Lane)
+
+
+
+ If CREATE USER MAPPING is executed in an extension
+ script, an extension dependency was created for the user mapping,
+ which is unexpected. Roles can't be extension members, so user
+ mappings shouldn't be either.
+
+
+
+
+
+
+ Make syslogger more robust against failures in opening CSV log files
+ (Tom Lane)
+
+
+
+
+
+
+ When libpq is given multiple target host
+ names, do the DNS lookups one at a time, not all at once (Tom Lane)
+
+
+
+ This prevents unnecessary failures or slow connections when a
+ connection is successfully made to one of the earlier servers in the
+ list.
+
+
+
+
+
+
+ Fix libpq's handling of connection timeouts
+ so that they are properly applied per host name or IP address (Tom Lane)
+
+
+
+ Previously, some code paths failed to restart the timer when switching
+ to a new target host, possibly resulting in premature timeout.
+
+
+
+
+
+ Fix psql, as well as documentation
+ examples, to call PQconsumeInput() before
+ each PQnotifies() call (Tom Lane)
+
+
+
+ This fixes cases in which psql would not
+ report receipt of a NOTIFY message until after the
+ next command.
+
+
+
+
+
+
+ Fix pg_dump's
+ option to also ignore publication
+ tables (Gilles Darold)
+
+
+
+
+
+
+ In pg_dump, exclude identity sequences when
+ their parent table is excluded from the dump (David Rowley)
+
+
+
+
+
+ Ensure proper quoting of transition table names
+ when pg_dump emits CREATE TRIGGER
+ ... REFERENCING commands (Tom Lane)
+
+
+
+
+
+
+ Fix possible inconsistency in pg_dump's
+ sorting of dissimilar object names (Jacob Champion)
+
+
+
+
+
+
+ Ensure that pg_restore will schema-qualify
+ the table name when
+ emitting DISABLE/ENABLE TRIGGER
+ commands (Tom Lane)
+
+
+
+ This avoids failures due to the new policy of running restores with
+ restrictive search path.
+
+
+
+
+
+
+ Fix pg_upgrade to handle event triggers in
+ extensions correctly (Haribabu Kommi)
+
+
+
+ pg_upgrade failed to preserve an event
+ trigger's extension-membership status.
+
+
+
+
+
+
+ Fix pg_upgrade's cluster state check to
+ work correctly on a standby server (Bruce Momjian)
+
+
+
+
+
+
+ Enforce type cube's dimension limit in
+ all contrib/cube functions (Andrey Borodin)
+
+
+
+ Previously, some cube-related functions could construct values that
+ would be rejected by cube_in(), leading to
+ dump/reload failures.
+
+
+
+
+
+
+ In contrib/pg_stat_statements, disallow
+ the pg_read_all_stats role from
+ executing pg_stat_statements_reset()
+ (Haribabu Kommi)
+
+
+
+ pg_read_all_stats is only meant to grant permission
+ to read statistics, not to change them, so this grant was incorrect.
+ To cause this change to take effect, run ALTER EXTENSION
+ pg_stat_statements UPDATE in each database
+ where pg_stat_statements has been installed.
+
+
+
+
+
+
+ In contrib/postgres_fdw, don't try to ship a
+ variable-free ORDER BY clause to the remote server
+ (Andrew Gierth)
+
+
+
+
+
+
+ Fix contrib/unaccent's
+ unaccent() function to use
+ the unaccent text search dictionary that is in the
+ same schema as the function (Tom Lane)
+
+
+
+ Previously it tried to look up the dictionary using the search path,
+ which could fail if the search path has a restrictive value.
+
+
+
+
+
+ Fix build problems on macOS 10.14 (Mojave) (Tom Lane)
+
+
+
+ Adjust configure to add
+ an switch to CPPFLAGS;
+ without this, PL/Perl and PL/Tcl fail to configure or build on macOS
+ 10.14. The specific sysroot used can be overridden at configure time
+ or build time by setting the PG_SYSROOT variable in
+ the arguments of configure
+ or make.
+
+
+
+ It is now recommended that Perl-related extensions
+ write $(perl_includespec) rather
+ than -I$(perl_archlibexp)/CORE in their compiler
+ flags. The latter continues to work on most platforms, but not recent
+ macOS.
+
+
+
+ Also, it should no longer be necessary to
+ specify manually to get PL/Tcl to
+ build on recent macOS releases.
+
+
+
+
+
+ Fix MSVC build and regression-test scripts to work on recent Perl
+ versions (Andrew Dunstan)
+
+
+
+ Perl no longer includes the current directory in its search path
+ by default; work around that.
+
+
+
+
+
+ On Windows, allow the regression tests to be run by an Administrator
+ account (Andrew Dunstan)
+
+
+
+ To do this safely, pg_regress now gives up
+ any such privileges at startup.
+
+
+
+
+
+
+ Allow btree comparison functions to return INT_MIN
+ (Tom Lane)
+
+
+
+ Up 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)
+
+
+
+ This error could, for example, result in failure to access a system
+ catalog or index that had just been processed by VACUUM
+ FULL.
+
+
+
+ This 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.
+
+
+
+
+
+
+ Save and restore SPI's global variables
+ during SPI_connect()
+ and SPI_finish() (Chapman Flack, Tom Lane)
+
+
+
+ This prevents possible interference when one SPI-using function calls
+ another.
+
+
+
+
+
+
+ Avoid using potentially-under-aligned page buffers (Tom Lane)
+
+
+
+ Invent new union types PGAlignedBlock
+ and PGAlignedXLogBlock, and use these in place of plain
+ char arrays, ensuring that the compiler can't place the buffer at a
+ misaligned start address. This fixes potential core dumps on
+ alignment-picky platforms, and may improve performance even on
+ platforms that allow misalignment.
+
+
+
+
+
+
+ Make src/port/snprintf.c follow the C99
+ standard's definition of snprintf()'s result
+ value (Tom Lane)
+
+
+
+ On platforms where this code is used (mostly Windows), its pre-C99
+ behavior could lead to failure to detect buffer overrun, if the
+ calling code assumed C99 semantics.
+
+
+
+
+
+
+ When building on i386 with the clang
+ compiler, require to be used (Andres Freund)
+
+
+
+ This avoids problems with missed floating point overflow checks.
+
+
+
+
+
+
+ Fix configure's detection of the result
+ type of strerror_r() (Tom Lane)
+
+
+
+ The previous coding got the wrong answer when building
+ with icc on Linux (and perhaps in other
+ cases), leading to libpq not returning
+ useful error messages for system-reported errors.
+
+
+
+
+
+ Update time zone data files to tzdata
+ release 2018g for DST law changes in Chile, Fiji, Morocco, and Russia
+ (Volgograd), plus historical corrections for China, Hawaii, Japan,
+ Macau, and North Korea.

+ Changes
+
+
+
+
+
+
+ Apply the tablespace specified for a partitioned index when creating a
+ child index (Álvaro Herrera)
+
+
+
+ Previously, child indexes were always created in the default
+ tablespace.
+
+
+
+
+
+
+ Fix NULL handling in parallel hashed multi-batch left joins (Andrew
+ Gierth, Thomas Munro)
+
+
+
+ Outer-relation rows with null values of the hash key were omitted from
+ the join result.
+
+
+
+
+
+
+ Fix incorrect processing of an array-type coercion expression
+ appearing within a CASE clause that has a constant
+ test expression (Tom Lane)
+
+
+
+
+
+
+ Fix incorrect expansion of tuples lacking recently-added columns
+ (Andrew Dunstan, Amit Langote)
+
+
+
+ This is known to lead to crashes in triggers on tables with
+ recently-added columns, and could have other symptoms as well.
+
+
+
+
+
+
+ Fix bugs with named or defaulted arguments in CALL
+ argument lists (Tom Lane, Pavel Stehule)
+
+
+
+
+
+
+ Fix strictness check for strict aggregates with ORDER
+ BY columns (Andrew Gierth, Andres Freund)
+
+
+
+ The strictness logic incorrectly ignored rows for which
+ the ORDER BY value(s) were null.
+
+
+

+ after rewinding the referenced cursor (Tom Lane)
+
+
+
+ A cursor that scans multiple relations (particularly an inheritance
+ tree) could produce wrong behavior if rewound to an earlier relation.
+
+
+
+
+
+ Fix EvalPlanQual to handle conditionally-executed
+ InitPlans properly (Andrew Gierth, Tom Lane)
+
+
+
+ This resulted in hard-to-reproduce crashes or wrong answers in
+ concurrent updates, if they contained code such as an uncorrelated
+ sub-SELECT inside a CASE
+ construct.
+
+
+
+
+
+ Fix character-class checks to not fail on Windows for Unicode
+ characters above U+FFFF (Tom Lane, Kenji Uno)
+
+
+
+ This bug affected full-text-search operations, as well
+ as contrib/ltree
+ and contrib/pg_trgm.
+
+
+
+
+
+ Ensure that sequences owned by a foreign table are processed
+ by ALTER OWNER on the table (Peter Eisentraut)
+
+
+
+ The ownership change should propagate to such sequences as well, but
+ this was missed for foreign tables.
+
+
+
+
+
+ Fix over-allocation of space for array_out()'s
+ result string (Keiichi Hirobe)
+
+
+
+
+
+ Fix memory leak in repeated SP-GiST index scans (Tom Lane)
+
+
+
+ This is only known to amount to anything significant in cases where
+ an exclusion constraint using SP-GiST receives many new index entries
+ in a single command.
+
+
+
+
+
+ Avoid crash if a utility command causes infinite recursion (Tom Lane)
+
+
+
+
+
+ When initializing a hot standby, cope with duplicate XIDs caused by
+ two-phase transactions on the master
+ (Michael Paquier, Konstantin Knizhnik)
+
+
+
+
+
+ Randomize the random() seed in bootstrap and
+ standalone backends, and in initdb
+ (Noah Misch)
+
+
+
+ The main practical effect of this change is that it avoids a scenario
+ where initdb might mistakenly conclude that
+ POSIX shared memory is not available, due to name collisions caused by
+ always using the same random seed.
+
+
+
+
+
+ Ensure that hot standby processes use the correct WAL consistency
+ point (Alexander Kukushkin, Michael Paquier)
+
+
+
+ This prevents possible misbehavior just after a standby server has
+ reached a consistent database state during WAL replay.
+
+
+
+
+
+ Don't run atexit callbacks when servicing SIGQUIT
+ (Heikki Linnakangas)
+
+
+
+
+
+ Don't record foreign-server user mappings as members of extensions
+ (Tom Lane)
+
+
+
+ If CREATE USER MAPPING is executed in an extension
+ script, an extension dependency was created for the user mapping,
+ which is unexpected. Roles can't be extension members, so user
+ mappings shouldn't be either.
+
+
+
+
+
+ Make syslogger more robust against failures in opening CSV log files
+ (Tom Lane)
+
+
+
+
+
+ Fix possible inconsistency in pg_dump's
+ sorting of dissimilar object names (Jacob Champion)
+
+
+
+
+
+ Ensure that pg_restore will schema-qualify
+ the table name when
+ emitting DISABLE/ENABLE TRIGGER
+ commands (Tom Lane)
+
+
+
+ This avoids failures due to the new policy of running restores with
+ restrictive search path.
+
+
+
+
+
+ Fix pg_upgrade to handle event triggers in
+ extensions correctly (Haribabu Kommi)
+
+
+
+ pg_upgrade failed to preserve an event
+ trigger's extension-membership status.
+
+
+
+
+
+ Fix pg_upgrade's cluster state check to
+ work correctly on a standby server (Bruce Momjian)
+
+
+
+
+
+ Enforce type cube's dimension limit in
+ all contrib/cube functions (Andrey Borodin)
+
+
+
+ Previously, some cube-related functions could construct values that
+ would be rejected by cube_in(), leading to
+ dump/reload failures.
+
+
+
+
+
+ Fix contrib/unaccent's
+ unaccent() function to use
+ the unaccent text search dictionary that is in the
+ same schema as the function (Tom Lane)
+
+
+
+ Previously it tried to look up the dictionary using the search path,
+ which could fail if the search path has a restrictive value.
+
+
+
+
+
+ Fix build problems on macOS 10.14 (Mojave) (Tom Lane)
+
+
+
+ Adjust configure to add
+ an switch to CPPFLAGS;
+ without this, PL/Perl and PL/Tcl fail to configure or build on macOS
+ 10.14. The specific sysroot used can be overridden at configure time
+ or build time by setting the PG_SYSROOT variable in
+ the arguments of configure
+ or make.
+
+
+
+ It is now recommended that Perl-related extensions
+ write $(perl_includespec) rather
+ than -I$(perl_archlibexp)/CORE in their compiler
+ flags. The latter continues to work on most platforms, but not recent
+ macOS.
+
+
+
+ Also, it should no longer be necessary to
+ specify manually to get PL/Tcl to
+ build on recent macOS releases.
+
+
+
+
+
+ Fix MSVC build and regression-test scripts to work on recent Perl
+ versions (Andrew Dunstan)
+
+
+
+ Perl no longer includes the current directory in its search path
+ by default; work around that.
+
+
+
+
+
+ Support building on Windows with Visual Studio 2015 or Visual Studio 2017
+ (Michael Paquier, Haribabu Kommi)
+
+
+
+
+
+ Allow btree comparison functions to return INT_MIN
+ (Tom Lane)
+
+
+
+ Up 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)
+
+
+
+ This error could, for example, result in failure to access a system
+ catalog or index that had just been processed by VACUUM
+ FULL.
+
+
+
+ This 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.
+
+
+
+
+
+ Save and restore SPI's global variables
+ during SPI_connect()
+ and SPI_finish() (Chapman Flack, Tom Lane)
+
+
+
+ This prevents possible interference when one SPI-using function calls
+ another.
+
+
+
+
+
+ Provide ALLOCSET_DEFAULT_SIZES and sibling macros
+ in back branches (Tom Lane)
+
+
+
+ These macros have existed since 9.6, but there were requests to add
+ them to older branches to allow extensions to rely on them without
+ branch-specific coding.
+
+
+
+
+
+ Avoid using potentially-under-aligned page buffers (Tom Lane)
+
+
+
+ Invent new union types PGAlignedBlock
+ and PGAlignedXLogBlock, and use these in place of plain
+ char arrays, ensuring that the compiler can't place the buffer at a
+ misaligned start address. This fixes potential core dumps on
+ alignment-picky platforms, and may improve performance even on
+ platforms that allow misalignment.
+
+
+
+
+
+ Make src/port/snprintf.c follow the C99
+ standard's definition of snprintf()'s result
+ value (Tom Lane)
+
+
+
+ On platforms where this code is used (mostly Windows), its pre-C99
+ behavior could lead to failure to detect buffer overrun, if the
+ calling code assumed C99 semantics.
+
+
+
+
+
+ When building on i386 with the clang
+ compiler, require to be used (Andres Freund)
+
+
+
+ This avoids problems with missed floating point overflow checks.
+
+
+
+
+
+ Fix configure's detection of the result
+ type of strerror_r() (Tom Lane)
+
+
+
+ The previous coding got the wrong answer when building
+ with icc on Linux (and perhaps in other
+ cases), leading to libpq not returning
+ useful error messages for system-reported errors.
+
+
+
+
+
+ Update time zone data files to tzdata
+ release 2018g for DST law changes in Chile, Fiji, Morocco, and Russia
+ (Volgograd), plus historical corrections for China, Hawaii, Japan,
+ Macau, and North Korea.

+ Changes
+
+
+
+
+
+ Fix corner-case failures
+ in has_foo_privilege()

+
+
+
+ Return NULL rather than throwing an error when an invalid object OID

+
+
+
+ Previously, the file descriptor was leaked, eventually resulting in

+
+
+

+ (Andres Freund)

+
+ Avoid possible buffer overrun when replaying GIN page recompression
+ from WAL (Alexander Korotkov, Sivasubramanian Ramasubramanian)
+
+
+
+
+
+ Fix missed fsync of a replication slot's directory (Konstantin
+ Knizhnik, Michael Paquier)
+
+
+
+
+
+ Fix unexpected timeouts when
+ using wal_sender_timeout on a slow server
+ (Noah Misch)
+
+
+
+
+
+ Ensure that hot standby processes use the correct WAL consistency
+ point (Alexander Kukushkin, Michael Paquier)
+
+
+
+ This prevents possible misbehavior just after a standby server has
+ reached a consistent database state during WAL replay.
+
+
+
+
+
+ Ensure background workers are stopped properly when the postmaster
+ receives a fast-shutdown request before completing database startup
+ (Alexander Kukushkin)
+
+
+
+
+
+ Don't run atexit callbacks when servicing SIGQUIT
+ (Heikki Linnakangas)
+
+
+
+
+
+ Don't record foreign-server user mappings as members of extensions
+ (Tom Lane)
+
+
+
+ If CREATE USER MAPPING is executed in an extension
+ script, an extension dependency was created for the user mapping,
+ which is unexpected. Roles can't be extension members, so user
+ mappings shouldn't be either.
+
+
+
+
+
+ Make syslogger more robust against failures in opening CSV log files
+ (Tom Lane)
+
+
+
+
+
+ Fix psql, as well as documentation
+ examples, to call PQconsumeInput() before
+ each PQnotifies() call (Tom Lane)
+
+
+
+ This fixes cases in which psql would not
+ report receipt of a NOTIFY message until after the
+ next command.
+
+
+
+
+
+ Fix possible inconsistency in pg_dump's
+ sorting of dissimilar object names (Jacob Champion)
+
+
+
+
+
+ Ensure that pg_restore will schema-qualify
+ the table name when
+ emitting DISABLE/ENABLE TRIGGER
+ commands (Tom Lane)
+
+
+
+ This avoids failures due to the new policy of running restores with
+ restrictive search path.
+
+
+
+
+
+ Fix pg_upgrade to handle event triggers in
+ extensions correctly (Haribabu Kommi)
+
+
+
+ pg_upgrade failed to preserve an event
+ trigger's extension-membership status.
+
+
+
+
+
+ Fix pg_upgrade's cluster state check to
+ work correctly on a standby server (Bruce Momjian)
+
+
+
+
+
+ Enforce type cube's dimension limit in
+ all contrib/cube functions (Andrey Borodin)
+
+
+
+ Previously, some cube-related functions could construct values that
+ would be rejected by cube_in(), leading to
+ dump/reload failures.
+
+
+
+
+
+ Fix contrib/unaccent's
+ unaccent() function to use
+ the unaccent text search dictionary that is in the
+ same schema as the function (Tom Lane)
+
+
+
+ Previously it tried to look up the dictionary using the search path,
+ which could fail if the search path has a restrictive value.
+
+
+
+
+
+ Fix build problems on macOS 10.14 (Mojave) (Tom Lane)
+
+
+
+ Adjust configure to add
+ an switch to CPPFLAGS;
+ without this, PL/Perl and PL/Tcl fail to configure or build on macOS
+ 10.14. The specific sysroot used can be overridden at configure time
+ or build time by setting the PG_SYSROOT variable in
+ the arguments of configure
+ or make.
+
+
+
+ It is now recommended that Perl-related extensions
+ write $(perl_includespec) rather
+ than -I$(perl_archlibexp)/CORE in their compiler
+ flags. The latter continues to work on most platforms, but not recent
+ macOS.
+
+
+
+ Also, it should no longer be necessary to
+ specify manually to get PL/Tcl to
+ build on recent macOS releases.
+
+
+
+
+
+ Fix MSVC build and regression-test scripts to work on recent Perl
+ versions (Andrew Dunstan)
+
+
+
+ Perl no longer includes the current directory in its search path
+ by default; work around that.
+
+
+
+
+
+ On Windows, allow the regression tests to be run by an Administrator
+ account (Andrew Dunstan)
+
+
+
+ To do this safely, pg_regress now gives up
+ any such privileges at startup.
+
+
+
+
+
+
+ Support building on Windows with Visual Studio 2015 or Visual Studio 2017
+ (Michael Paquier, Haribabu Kommi)
+
+
+
+
+
+ Allow btree comparison functions to return INT_MIN
+ (Tom Lane)
+
+
+
+ Up 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)
+
+
+
+ This error could, for example, result in failure to access a system
+ catalog or index that had just been processed by VACUUM
+ FULL.
+
+
+
+ This 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.
+
+
+
+
+
+ Save and restore SPI's global variables
+ during SPI_connect()
+ and SPI_finish() (Chapman Flack, Tom Lane)
+
+
+
+ This prevents possible interference when one SPI-using function calls
+ another.
+
+
+
+
+
+
+ Provide ALLOCSET_DEFAULT_SIZES and sibling macros
+ in back branches (Tom Lane)
+
+
+
+ These macros have existed since 9.6, but there were requests to add
+ them to older branches to allow extensions to rely on them without
+ branch-specific coding.
+
+
+
+
+
+ Avoid using potentially-under-aligned page buffers (Tom Lane)
+
+
+
+ Invent new union types PGAlignedBlock
+ and PGAlignedXLogBlock, and use these in place of plain
+ char arrays, ensuring that the compiler can't place the buffer at a
+ misaligned start address. This fixes potential core dumps on
+ alignment-picky platforms, and may improve performance even on
+ platforms that allow misalignment.
+
+
+
+
+
+ Make src/port/snprintf.c follow the C99
+ standard's definition of snprintf()'s result
+ value (Tom Lane)
+
+
+
+ On platforms where this code is used (mostly Windows), its pre-C99
+ behavior could lead to failure to detect buffer overrun, if the
+ calling code assumed C99 semantics.
+
+
+
+
+
+ When building on i386 with the clang
+ compiler, require to be used (Andres Freund)
+
+
+
+ This avoids problems with missed floating point overflow checks.
+
+
+
+
+
+ Fix configure's detection of the result
+ type of strerror_r() (Tom Lane)
+
+
+
+ The previous coding got the wrong answer when building
+ with icc on Linux (and perhaps in other
+ cases), leading to libpq not returning
+ useful error messages for system-reported errors.
+
+
+
+
+
+ Update time zone data files to tzdata
+ release 2018g for DST law changes in Chile, Fiji, Morocco, and Russia
+ (Volgograd), plus historical corrections for China, Hawaii, Japan,
+ Macau, and North Korea.

+
+ Release 9.6.11
+
+
+ Release date:
+ 2018-11-08
+
+
+
+ This release contains a variety of fixes from 9.6.10.
+ For information about new features in the 9.6 major release, see
+ .
+
+
+
+ Migration to Version 9.6.11
+
+
+ A dump/restore is not required for those running 9.6.X.
+
+
+
+ However, if you are upgrading from a version earlier than 9.6.9,
+ see .
+
+
+
+
+ Changes
+
+
+
+
+
+ Fix corner-case failures
+ in has_foo_privilege()
+ family of functions (Tom Lane)
+
+
+
+ Return NULL rather than throwing an error when an invalid object OID
+ is provided. Some of these functions got that right already, but not
+ all. has_column_privilege() was additionally
+ capable of crashing on some platforms.
+
+
+
+
+
+ Avoid O(N^2) slowdown in regular expression match/split functions on
+ long strings (Andrew Gierth)
+
+
+
+
+
+ Fix parsing of standard multi-character operators that are immediately
+ followed by a comment or + or -
+ (Andrew Gierth)
+
+
+
+ This oversight could lead to parse errors, or to incorrect assignment
+ of precedence.
+
+
+
+
+
+ Avoid O(N^3) slowdown in lexer for long strings
+ of + or - characters
+ (Andrew Gierth)
+
+
+
+
+
+ Fix mis-execution of SubPlans when the outer query is being scanned
+ backwards (Andrew Gierth)
+
+
+
+
+
+ Fix failure of UPDATE/DELETE ... WHERE CURRENT OF ...
+ after rewinding the referenced cursor (Tom Lane)
+
+
+
+ A cursor that scans multiple relations (particularly an inheritance
+ tree) could produce wrong behavior if rewound to an earlier relation.
+
+
+
+
+
+ Fix EvalPlanQual to handle conditionally-executed
+ InitPlans properly (Andrew Gierth, Tom Lane)
+
+
+
+ This resulted in hard-to-reproduce crashes or wrong answers in
+ concurrent updates, if they contained code such as an uncorrelated
+ sub-SELECT inside a CASE
+ construct.
+
+
+
+
+
+ Fix character-class checks to not fail on Windows for Unicode
+ characters above U+FFFF (Tom Lane, Kenji Uno)
+
+
+
+ This bug affected full-text-search operations, as well
+ as contrib/ltree
+ and contrib/pg_trgm.
+
+
+
+
+
+ Disallow pushing sub-SELECTs containing window
+ functions, LIMIT, or OFFSET to
+ parallel workers (Amit Kapila)
+
+
+
+ Such cases could result in inconsistent behavior due to different
+ workers getting different answers, as a result of indeterminacy
+ due to row-ordering variations.
+
+
+
+
+
+ Ensure that sequences owned by a foreign table are processed
+ by ALTER OWNER on the table (Peter Eisentraut)
+
+
+
+ The ownership change should propagate to such sequences as well, but
+ this was missed for foreign tables.
+
+
+
+
+
+ Ensure that the server will process
+ already-received NOTIFY
+ and SIGTERM interrupts before waiting for client
+ input (Jeff Janes, Tom Lane)
+
+
+
+
+
+ Fix over-allocation of space for array_out()'s
+ result string (Keiichi Hirobe)
+
+
+
+
+
+ Fix memory leak in repeated SP-GiST index scans (Tom Lane)
+
+
+
+ This is only known to amount to anything significant in cases where
+ an exclusion constraint using SP-GiST receives many new index entries
+ in a single command.
+
+
+
+
+
+ Ensure that ApplyLogicalMappingFile() closes the
+ mapping file when done with it (Tomas Vondra)
+
+
+
+ Previously, the file descriptor was leaked, eventually resulting in
+ failures during logical decoding.
+
+
+
+
+
+ Fix logical decoding to handle cases where a mapped catalog table is
+ repeatedly rewritten, e.g. by VACUUM FULL
+ (Andres Freund)
+
+
+
+
+
+ Prevent starting the server with wal_level set
+ to too low a value to support an existing replication slot (Andres
+ Freund)
+
+
+
+
+
+ Avoid crash if a utility command causes infinite recursion (Tom Lane)
+
+
+
+
+
+ When initializing a hot standby, cope with duplicate XIDs caused by
+ two-phase transactions on the master
+ (Michael Paquier, Konstantin Knizhnik)
+
+
+
+
+
+ Fix event triggers to handle nested ALTER TABLE
+ commands (Michael Paquier, Álvaro Herrera)
+
+
+
+
+
+ Propagate parent process's transaction and statement start timestamps
+ to parallel workers (Konstantin Knizhnik)
+
+
+
+ This prevents misbehavior of functions such
+ as transaction_timestamp() when executed in a
+ worker.
+
+
+
+
+
+ Fix transfer of expanded datums to parallel workers so that alignment
+ is preserved, preventing crashes on alignment-picky platforms
+ (Tom Lane, Amit Kapila)
+
+
+
+
+
+ Fix WAL file recycling logic to work correctly on standby servers
+ (Michael Paquier)
+
+
+
+ Depending on the setting of archive_mode, a standby
+ might fail to remove some WAL files that could be removed.
+
+
+
+
+
+ Fix handling of commit-timestamp tracking during recovery
+ (Masahiko Sawasa, Michael Paquier)
+
+
+
+ If commit timestamp tracking has been turned on or off, recovery might
+ fail due to trying to fetch the commit timestamp for a transaction
+ that did not record it.
+
+
+
+
+
+ Randomize the random() seed in bootstrap and
+ standalone backends, and in initdb
+ (Noah Misch)
+
+
+
+ The main practical effect of this change is that it avoids a scenario
+ where initdb might mistakenly conclude that
+ POSIX shared memory is not available, due to name collisions caused by
+ always using the same random seed.
+
+
+
+
+
+ Allow DSM allocation to be interrupted (Chris Travers)
+
+
+
+
+
+ Avoid failure in a parallel worker when loading an extension that
+ tries to access system caches within its init function (Thomas Munro)
+
+
+
+ We don't consider that to be good extension coding practice, but it
+ mostly worked before parallel query, so continue to support it for
+ now.
+
+
+
+
+
+ Properly handle turning full_page_writes on
+ dynamically (Kyotaro Horiguchi)
+
+
+
+
+
+ Fix possible crash due to double free() during
+ SP-GiST rescan (Andrew Gierth)
+
+
+
+
+
+ Avoid possible buffer overrun when replaying GIN page recompression
+ from WAL (Alexander Korotkov, Sivasubramanian Ramasubramanian)
+
+
+
+
+
+ Fix missed fsync of a replication slot's directory (Konstantin
+ Knizhnik, Michael Paquier)
+
+
+
+
+
+ Fix unexpected timeouts when
+ using wal_sender_timeout on a slow server
+ (Noah Misch)
+
+
+
+
+
+ Ensure that hot standby processes use the correct WAL consistency
+ point (Alexander Kukushkin, Michael Paquier)
+
+
+
+ This prevents possible misbehavior just after a standby server has
+ reached a consistent database state during WAL replay.
+
+
+
+
+
+ Ensure background workers are stopped properly when the postmaster
+ receives a fast-shutdown request before completing database startup
+ (Alexander Kukushkin)
+
+
+
+
+
+ Update the free space map during WAL replay of page all-visible/frozen
+ flag changes (Álvaro Herrera)
+
+
+
+ Previously we were not careful about this, reasoning that the FSM is
+ not critical data anyway. However, if it's sufficiently out of date,
+ that can result in significant performance degradation after a standby
+ has been promoted to primary. The FSM will eventually be healed by
+ updates, but we'd like it to be good sooner, so work harder at
+ maintaining it during WAL replay.
+
+
+
+
+
+ Avoid premature release of parallel-query resources when query end or
+ tuple count limit is reached (Amit Kapila)
+
+
+
+ It's only okay to shut down the executor at this point if the caller
+ cannot demand backwards scan afterwards.
+
+
+
+
+
+ Don't run atexit callbacks when servicing SIGQUIT
+ (Heikki Linnakangas)
+
+
+
+
+
+ Don't record foreign-server user mappings as members of extensions
+ (Tom Lane)
+
+
+
+ If CREATE USER MAPPING is executed in an extension
+ script, an extension dependency was created for the user mapping,
+ which is unexpected. Roles can't be extension members, so user
+ mappings shouldn't be either.
+
+
+
+
+
+ Make syslogger more robust against failures in opening CSV log files
+ (Tom Lane)
+
+
+
+
+
+ Fix psql, as well as documentation
+ examples, to call PQconsumeInput() before
+ each PQnotifies() call (Tom Lane)
+
+
+
+ This fixes cases in which psql would not
+ report receipt of a NOTIFY message until after the
+ next command.
+
+
+
+
+
+ Fix possible inconsistency in pg_dump's
+ sorting of dissimilar object names (Jacob Champion)
+
+
+
+
+
+ Ensure that pg_restore will schema-qualify
+ the table name when
+ emitting DISABLE/ENABLE TRIGGER
+ commands (Tom Lane)
+
+
+
+ This avoids failures due to the new policy of running restores with
+ restrictive search path.
+
+
+
+
+
+ Fix pg_upgrade to handle event triggers in
+ extensions correctly (Haribabu Kommi)
+
+
+
+ pg_upgrade failed to preserve an event
+ trigger's extension-membership status.
+
+
+
+
+
+ Fix pg_upgrade's cluster state check to
+ work correctly on a standby server (Bruce Momjian)
+
+
+
+
+
+ Enforce type cube's dimension limit in
+ all contrib/cube functions (Andrey Borodin)
+
+
+
+ Previously, some cube-related functions could construct values that
+ would be rejected by cube_in(), leading to
+ dump/reload failures.
+
+
+
+
+
+ In contrib/postgres_fdw, don't try to ship a
+ variable-free ORDER BY clause to the remote server
+ (Andrew Gierth)
+
+
+
+
+
+ Fix contrib/unaccent's
+ unaccent() function to use
+ the unaccent text search dictionary that is in the
+ same schema as the function (Tom Lane)
+
+
+
+ Previously it tried to look up the dictionary using the search path,
+ which could fail if the search path has a restrictive value.
+
+
+
+
+
+ Fix build problems on macOS 10.14 (Mojave) (Tom Lane)
+
+
+
+ Adjust configure to add
+ an switch to CPPFLAGS;
+ without this, PL/Perl and PL/Tcl fail to configure or build on macOS
+ 10.14. The specific sysroot used can be overridden at configure time
+ or build time by setting the PG_SYSROOT variable in
+ the arguments of configure
+ or make.
+
+
+

+ 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)
+
+
+
+ This error could, for example, result in failure to access a system
+ catalog or index that had just been processed by VACUUM
+ FULL.
+
+
+
+ This 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.
+
+
