+ Release 9.1.24
+
+
+ Release Date
+ 2016-10-27
+
+
+
+ This release contains a variety of fixes from 9.1.23.
+ For information about new features in the 9.1 major release, see
+ .
+
+
+
+ This is expected to be the last PostgreSQL release
+ in the 9.1.X series. Users are encouraged to update to a newer
+ release branch soon.
+
+
+
+ Migration to Version 9.1.24
+
+
+ A dump/restore is not required for those running 9.1.X.
+
+
+
+ However, if you are upgrading from a version earlier than 9.1.16,
+ see .
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Fix EvalPlanQual rechecks involving CTE scans (Tom Lane)
+
+
+
+ The recheck would always see the CTE as returning no rows, typically
+ leading to failure to update rows that were recently updated.
+
+
+
+
+
+ Fix improper repetition of previous results from hashed aggregation in
+ a subquery (Andrew Gierth)
+
+
+
+ The test to see if we can reuse a previously-computed hash table of
+ the aggregate state values neglected the possibility of an outer query
+ reference appearing in an aggregate argument expression. A change in
+ the value of such a reference should lead to recalculating the hash
+ table, but did not.
+
+
+
+
+
+ Fix timeout length when VACUUM is waiting for exclusive
+ table lock so that it can truncate the table (Simon Riggs)
+
+
+
+ The timeout was meant to be 50 milliseconds, but it was actually only
+ 50 microseconds, causing VACUUM to give up on truncation
+ much more easily than intended. Set it to the intended value.
+
+
+
+
+
+ Remove artificial restrictions on the values accepted
+ by numeric_in() and numeric_recv()
+ (Tom Lane)
+
+
+
+ We allow numeric values up to the limit of the storage format (more
+ than 1e100000), so it seems fairly pointless
+ that numeric_in() rejected scientific-notation exponents
+ above 1000. Likewise, it was silly for numeric_recv() to
+ reject more than 1000 digits in an input value.
+
+
+
+
+
+ Avoid very-low-probability data corruption due to testing tuple
+ visibility without holding buffer lock (Thomas Munro, Peter Geoghegan,
+ Tom Lane)
+
+
+
+
+
+ Fix file descriptor leakage when truncating a temporary relation of
+ more than 1GB (Andres Freund)
+
+
+
+
+
+ Disallow starting a standalone backend with standby_mode
+ turned on (Michael Paquier)
+
+
+
+ This can't do anything useful, since there will be no WAL receiver
+ process to fetch more WAL data; and it could result in misbehavior
+ in code that wasn't designed with this situation in mind.
+
+
+
+
+
+ Don't try to share SSL contexts across multiple connections
+ in libpq (Heikki Linnakangas)
+
+
+
+ This led to assorted corner-case bugs, particularly when trying to use
+ different SSL parameters for different connections.
+
+
+
+
+
+ Avoid corner-case memory leak in libpq (Tom Lane)
+
+
+
+ The reported problem involved leaking an error report
+ during PQreset(), but there might be related cases.
+
+
+
+
+
+ Make ecpg's
+
+
+
+
+ Fix contrib/intarray/bench/bench.pl to print the results
+ of the EXPLAIN it does when given the
+
+
+
+
+ Prevent failure of obsolete dynamic time zone abbreviations (Tom Lane)
+
+
+
+ If a dynamic time zone abbreviation does not match any entry in the
+ referenced time zone, treat it as equivalent to the time zone name.
+ This avoids unexpected failures when IANA removes abbreviations from
+ their time zone database, as they did in tzdata
+ release 2016f and seem likely to do again in the future. The
+ consequences were not limited to not recognizing the individual
+ abbreviation; any mismatch caused
+ the pg_timezone_abbrevs view to fail altogether.
+
+
+
+
+
+ Update time zone data files to tzdata release 2016h
+ for DST law changes in Palestine and Turkey, plus historical
+ corrections for Turkey and some regions of Russia.
+ Switch to numeric abbreviations for some time zones in Antarctica,
+ the former Soviet Union, and Sri Lanka.
+
+
+
+ The IANA time zone database previously provided textual abbreviations
+ for all time zones, sometimes making up abbreviations that have little
+ or no currency among the local population. They are in process of
+ reversing that policy in favor of using numeric UTC offsets in zones
+ where there is no evidence of real-world use of an English
+ abbreviation. At least for the time being, PostgreSQL
+ will continue to accept such removed abbreviations for timestamp input.
+ But they will not be shown in the pg_timezone_names
+ view nor used for output.
+
+
+
+ In this update, AMT is no longer shown as being in use to
+ mean Armenia Time. Therefore, we have changed the Default
+ abbreviation set to interpret it as Amazon Time, thus UTC-4 not UTC+4.

+
+ The test to see if we can reuse a previously-computed hash table of
+ the aggregate state values neglected the possibility of an outer query
+ reference appearing in an aggregate argument expression. A change in
+ the value of such a reference should lead to recalculating the hash
+ table, but did not.
+
+
+
+
+
+ Fix query-lifespan memory leak in a bulk UPDATE on a table
+ with a PRIMARY KEY or REPLICA IDENTITY index
+ (Tom Lane)
+
+
+
+
+
+ Fix EXPLAIN to emit valid XML when
+ is on (Markus Winand)
+
+
+
+ Previously the XML output-format option produced syntactically invalid
+ tags such as <I/O-Read-Time>. That is now
+ rendered as <I-O-Read-Time>.
+
+
+
+
+
+ Suppress printing of zeroes for unmeasured times
+ in EXPLAIN (Maksim Milyutin)
+
+
+
+ Certain option combinations resulted in printing zero values for times
+ that actually aren't ever measured in that combination. Our general
+ policy in EXPLAIN is not to print such fields at all, so
+ do that consistently in all cases.
+
+
+
+
+
+ Fix timeout length when VACUUM is waiting for exclusive
+ table lock so that it can truncate the table (Simon Riggs)
+
+
+
+ The timeout was meant to be 50 milliseconds, but it was actually only
+ 50 microseconds, causing VACUUM to give up on truncation
+ much more easily than intended. Set it to the intended value.
+
+
+
+
+
+ Fix bugs in merging inherited CHECK constraints while
+ creating or altering a table (Tom Lane, Amit Langote)
+
+
+
+ Allow identical CHECK constraints to be added to a parent
+ and child table in either order. Prevent merging of a valid
+ constraint from the parent table with a NOT VALID
+ constraint on the child. Likewise, prevent merging of a NO
+ INHERIT child constraint with an inherited constraint.
+
+
+
+
+
+ Remove artificial restrictions on the values accepted
+ by numeric_in() and numeric_recv()
+ (Tom Lane)
+
+
+
+ We allow numeric values up to the limit of the storage format (more
+ than 1e100000), so it seems fairly pointless
+ that numeric_in() rejected scientific-notation exponents
+ above 1000. Likewise, it was silly for numeric_recv() to
+ reject more than 1000 digits in an input value.
+
+
+
+
+
+ Avoid very-low-probability data corruption due to testing tuple
+ visibility without holding buffer lock (Thomas Munro, Peter Geoghegan,
+ Tom Lane)
+
+
+
+
+
+ Fix logical WAL decoding to work properly when a subtransaction's WAL
+ output is large enough to spill to disk (Andres Freund)
+
+
+
+
+
+
+ Fix buffer overread in logical WAL decoding (Tom Lane)
+
+
+
+ Logical decoding of a tuple update record read 23 bytes too many,
+ which was usually harmless but with very bad luck could result in a
+ crash.
+
+
+
+
+
+ Fix file descriptor leakage when truncating a temporary relation of
+ more than 1GB (Andres Freund)
+
+
+
+
+
+ Disallow starting a standalone backend with standby_mode
+ turned on (Michael Paquier)
+
+
+
+ This can't do anything useful, since there will be no WAL receiver
+ process to fetch more WAL data; and it could result in misbehavior
+ in code that wasn't designed with this situation in mind.
+
+
+
+
+
+ Properly initialize replication slot state when recycling a
+ previously-used slot (Michael Paquier)
+
+
+
+ This failure to reset all of the fields of the slot could
+ prevent VACUUM from removing dead tuples.
+
+
+
+
+
+ Round shared-memory allocation request to a multiple of the actual
+ huge page size when attempting to use huge pages on Linux (Tom Lane)
+
+
+
+ This avoids possible failures during munmap() on systems
+ with atypical default huge page sizes. Except in crash-recovery
+ cases, there were no ill effects other than a log message.
+
+
+
+
+
+ Use a more random value for the dynamic shared memory control
+ segment's ID (Robert Haas, Tom Lane)
+
+
+
+ Previously, the same value would be chosen every time, because it was
+ derived from random() but srandom() had not
+ yet been called. While relatively harmless, this was not the intended
+ behavior.
+
+
+
+
+
+ On Windows, retry creation of the dynamic shared memory control
+ segment after an access-denied error (Kyotaro Horiguchi, Amit Kapila)
+
+
+
+ Windows sometimes returns ERROR_ACCESS_DENIED rather
+ than ERROR_ALREADY_EXISTS when there is an existing
+ segment. This led to postmaster startup failure due to believing that
+ the former was an unrecoverable error.
+
+
+
+
+
+ Don't try to share SSL contexts across multiple connections
+ in libpq (Heikki Linnakangas)
+
+
+
+ This led to assorted corner-case bugs, particularly when trying to use
+ different SSL parameters for different connections.
+
+
+
+
+
+ Avoid corner-case memory leak in libpq (Tom Lane)
+
+
+
+ The reported problem involved leaking an error report
+ during PQreset(), but there might be related cases.

+ Fix pgbench's calculation of average latency
+ (Fabien Coelho)
+
+
+
+ The calculation was incorrect when there were \sleep
+ commands in the script, or when the test duration was specified in
+ number of transactions rather than total time.
+
+
+
+
+
+ In pg_dump, never dump range constructor functions
+ (Tom Lane)
+
+
+
+ This oversight led to pg_upgrade failures with
+ extensions containing range types, due to duplicate creation of the
+ constructor functions.

+ In pg_xlogdump, retry opening new WAL segments when

+
+
+ Fix pg_xlogdump to cope with a WAL file that begins
+ with a continuation record spanning more than one page (Pavan

+
+
+
+
+
+ Fix contrib/pg_buffercache to work
+ when shared_buffers exceeds 256GB (KaiGai Kohei)

+ added in recent Windows versions (Michael Paquier)
+
+
+
+
+
+ Prevent failure of obsolete dynamic time zone abbreviations (Tom Lane)
+
+
+
+ If a dynamic time zone abbreviation does not match any entry in the
+ referenced time zone, treat it as equivalent to the time zone name.
+ This avoids unexpected failures when IANA removes abbreviations from
+ their time zone database, as they did in tzdata
+ release 2016f and seem likely to do again in the future. The
+ consequences were not limited to not recognizing the individual
+ abbreviation; any mismatch caused
+ the pg_timezone_abbrevs view to fail altogether.
+
+
+
+
+
+ Update time zone data files to tzdata release 2016h
+ for DST law changes in Palestine and Turkey, plus historical
+ corrections for Turkey and some regions of Russia.
+ Switch to numeric abbreviations for some time zones in Antarctica,
+ the former Soviet Union, and Sri Lanka.
+
+
+
+ The IANA time zone database previously provided textual abbreviations
+ for all time zones, sometimes making up abbreviations that have little
+ or no currency among the local population. They are in process of
+ reversing that policy in favor of using numeric UTC offsets in zones
+ where there is no evidence of real-world use of an English
+ abbreviation. At least for the time being, PostgreSQL
+ will continue to accept such removed abbreviations for timestamp input.
+ But they will not be shown in the pg_timezone_names
+ view nor used for output.
+
+
+
+ In this update, AMT is no longer shown as being in use to
+ mean Armenia Time. Therefore, we have changed the Default
+ abbreviation set to interpret it as Amazon Time, thus UTC-4 not UTC+4.

+
+
+ Migration to Version 9.5.5
+

+ A dump/restore is not required for those running 9.5.X.
+
+
+
+ However, if your installation has been affected by the bug described in

+
+
+
+
+ Changes
+
+
+
+
+
+ Fix WAL-logging of truncation of relation free space maps and
+ visibility maps (Pavan Deolasee, Heikki Linnakangas)
+
+
+
+ It was possible for these files to not be correctly restored during
+ crash recovery, or to be written incorrectly on a standby server.
+ Bogus entries in a free space map could lead to attempts to access
+ pages that have been truncated away from the relation itself, typically
+ producing errors like could not read block XXX:
+ read only 0 of 8192 bytes. Checksum failures in the
+ visibility map are also possible, if checksumming is enabled.
+
+
+
+ Procedures for determining whether there is a problem and repairing it
+ if so are discussed at
+ .
+
+
+
+
+
+
+ Fix incorrect creation of GIN index WAL records on big-endian machines
+ (Tom Lane)
+
+
+
+ The typical symptom was unexpected GIN leaf action errors
+ during WAL replay.
+
+
+
+
+
+
+ Fix SELECT FOR UPDATE/SHARE to correctly lock tuples that
+ have been updated by a subsequently-aborted transaction
+ (Álvaro Herrera)
+
+
+
+ In 9.5 and later, the SELECT would sometimes fail to
+ return such tuples at all. A failure has not been proven to occur in
+ earlier releases, but might be possible with concurrent updates.
+
+
+
+
+
+
+ Fix EvalPlanQual rechecks involving CTE scans (Tom Lane)
+
+
+
+ The recheck would always see the CTE as returning no rows, typically
+ leading to failure to update rows that were recently updated.
+
+
+
+
+
+
+ Fix deletion of speculatively inserted TOAST tuples when backing out
+ of INSERT ... ON CONFLICT (Oskari Saarenmaa)
+
+
+
+ In the race condition where two transactions try to insert conflicting
+ tuples at about the same time, the loser would fail with
+ an attempted to delete invisible tuple error if its
+ insertion included any TOAST'ed fields.
+
+
+
+
+
+ Don't throw serialization errors for self-conflicting insertions
+ in INSERT ... ON CONFLICT (Thomas Munro, Peter Geoghegan)
+
+
+
+
+
+
+ Fix improper repetition of previous results from hashed aggregation in
+ a subquery (Andrew Gierth)
+
+
+
+ The test to see if we can reuse a previously-computed hash table of
+ the aggregate state values neglected the possibility of an outer query
+ reference appearing in an aggregate argument expression. A change in
+ the value of such a reference should lead to recalculating the hash
+ table, but did not.
+
+

+ with a PRIMARY KEY or REPLICA IDENTITY index

+ in pg_settings.unit

+
+
+
+ Fix possible data corruption when pg_upgrade rewrites
+ a relation visibility map into 9.6 format (Tom Lane)
+
+
+
+ On big-endian machines, bytes of the new visibility map were written
+ in the wrong order, leading to a completely incorrect map. On
+ Windows, the old map was read using text mode, leading to incorrect
+ results if the map happened to contain consecutive bytes that matched
+ a carriage return/line feed sequence. The latter error would almost
+ always lead to a pg_upgrade failure due to the map
+ file appearing to be the wrong length.
+
+
+
+ If you are using a big-endian machine (many non-Intel architectures
+ are big-endian) and have used pg_upgrade to upgrade
+ from a pre-9.6 release, you should assume that all visibility maps are
+ incorrect and need to be regenerated. It is sufficient to truncate
+ each relation's visibility map
+ with contrib/pg_visibility's
+ pg_truncate_visibility_map() function.

+

+ Fix incorrect handling of polymorphic aggregates used as window
+ functions (Tom Lane)
+
+
+
+ The aggregate's transition function was told that its first argument

+
+
+ Fix bugs in merging inherited CHECK constraints while
+ creating or altering a table (Tom Lane, Amit Langote)
+
+
+
+ Allow identical CHECK constraints to be added to a parent
+ and child table in either order. Prevent merging of a valid
+ constraint from the parent table with a NOT VALID
+ constraint on the child. Likewise, prevent merging of a NO
+ INHERIT child constraint with an inherited constraint.

+ Show a sensible value
+ in pg_settings.unit
+ for min_wal_size and max_wal_size (Tom Lane)

+
+ Fix replacement of array elements in jsonb_set()
+ (Tom Lane)
+
+
+
+ If the target is an existing JSON array element, it got deleted
+ instead of being replaced with a new value.

+ Avoid very-low-probability data corruption due to testing tuple
+ visibility without holding buffer lock (Thomas Munro, Peter Geoghegan,
+ Tom Lane)

+ Fix logical WAL decoding to work properly when a subtransaction's WAL
+ output is large enough to spill to disk (Andres Freund)

+
+ Round shared-memory allocation request to a multiple of the actual
+ huge page size when attempting to use huge pages on Linux (Tom Lane)
+
+
+
+ This avoids possible failures during munmap() on systems
+ with atypical default huge page sizes. Except in crash-recovery
+ cases, there were no ill effects other than a log message.
+
+
+
+
+
+
+ Don't try to share SSL contexts across multiple connections
+ in libpq (Heikki Linnakangas)
+
+
+
+ This led to assorted corner-case bugs, particularly when trying to use
+ different SSL parameters for different connections.
+
+
+
+
+
+
+ Avoid corner-case memory leak in libpq (Tom Lane)
+
+
+
+ The reported problem involved leaking an error report
+ during PQreset(), but there might be related cases.

+
+
+ In pg_upgrade, check library loadability in name order
+ (Tom Lane)
+
+
+
+ This is a workaround to deal with cross-extension dependencies from
+ language transform modules to their base language and data type
+ modules.
+
+
+
+
+
+
+ Fix pg_upgrade to work correctly for extensions
+ containing index access methods (Tom Lane)
+
+
+
+ To allow this, the server has been extended to support ALTER
+ EXTENSION ADD/DROP ACCESS METHOD. That functionality should have
+ been included in the original patch to support dynamic creation of
+ access methods, but it was overlooked.
+

+
+
+
+ Improve error reporting in pg_upgrade's file
+ copying/linking/rewriting steps (Tom Lane, Álvaro Herrera)
+
+
+
+
+
+
+ Fix pg_dump to work against pre-7.4 servers
+ (Amit Langote, Tom Lane)
+
+
+
+
+
+
+ Disallow specifying both
+
+
+
+
+
+ Make pg_rewind turn off synchronous_commit
+ in its session on the source server (Michael Banck, Michael Paquier)
+
+
+
+ This allows pg_rewind to work even when the source
+ server is using synchronous replication that is not working for some
+ reason.
+
+
+
+
+
+
+ In pg_xlogdump, retry opening new WAL segments when
+ using
+
+
+ This allows for a possible delay in the server's creation of the next
+ segment.

+
+ Fix contrib/pg_visibility to report the correct TID for
+ a corrupt tuple that has been the subject of a rolled-back update
+ (Tom Lane)
+
+
+
+
+
+
+ Fix makefile dependencies so that parallel make
+ of PL/Python by itself will succeed reliably
+ (Pavel Raiskup)
+
+
+
+
+
+
+ Update time zone data files to tzdata release 2016h
+ for DST law changes in Palestine and Turkey, plus historical
+ corrections for Turkey and some regions of Russia.
+ Switch to numeric abbreviations for some time zones in Antarctica,
+ the former Soviet Union, and Sri Lanka.
+
+
+
+ The IANA time zone database previously provided textual abbreviations
+ for all time zones, sometimes making up abbreviations that have little
+ or no currency among the local population. They are in process of
+ reversing that policy in favor of using numeric UTC offsets in zones
+ where there is no evidence of real-world use of an English
+ abbreviation. At least for the time being, PostgreSQL
+ will continue to accept such removed abbreviations for timestamp input.
+ But they will not be shown in the pg_timezone_names
+ view nor used for output.
+
+
+
+ In this update, AMT is no longer shown as being in use to
+ mean Armenia Time. Therefore, we have changed the Default
+ abbreviation set to interpret it as Amazon Time, thus UTC-4 not UTC+4.
