Release 10.11
+
+
+
Release date:
+
+
+ This release contains a variety of fixes from 10.10.
+ For information about new features in major release 10, see
+ .
+
+
+
+
Migration to Version 10.11
+
+ A dump/restore is not required for those running 10.X.
+
+
+ However, if you use the contrib/intarray
+ extension with a GiST index, and you rely on indexed searches
+ for the <@ operator, see the entry below
+ about that.
+
+
+ Also, if you are upgrading from a version earlier than 10.6,
+ see .

Changes
+
+
+
+
+
+ Fix failure of ALTER TABLE SET with a custom
+ relation option (Michael Paquier)
+
+
+
+
+
+ Disallow changing a multiply-inherited column's type if not all
+ parent tables were changed (Tom Lane)
+
+
+ Previously, this was allowed, whereupon queries on the
+ now-out-of-sync parent would fail.
+
+
+
+
+
+ Prevent VACUUM from trying to freeze
+ an old multixact ID involving a still-running transaction
+ (Nathan Bossart, Jeremy Schneider)
+
+
+ This case would lead to VACUUM failing until the
+ old transaction terminates.
+
+
+
+
+
+ Fix planner's test for case-foldable characters
+ in ILIKE with an ICU collation (Tom Lane)
+
+
+ This mistake caused the planner to treat too much of the pattern as
+ being a fixed prefix, so that indexscans derived from
+ an ILIKE clause might miss entries that they
+ should find.
+
+
+
+
+
+ Ensure that offset expressions in WINDOW clauses
+ are processed when a query's expressions are manipulated (Andrew Gierth)
+
+
+ This oversight could result in assorted failures when the offsets
+ are nontrivial expressions. One example is that a function
+ parameter reference in such an expression would fail if the function
+ was inlined.
+
+
+
+
+
+ Fix handling of whole-row variables in WITH CHECK
+ OPTION expressions and row-level-security policy expressions
+ (Andres Freund)
+
+
+ Previously, such usage might result in bogus errors about row type
+ mismatches.
+
+
+
+
+
+ Avoid postmaster failure if a parallel query requests a background
+ worker when no postmaster child process array slots remain free
+ (Tom Lane)
+
+
+
+
+
+ Prevent possible double-free if a BEFORE UPDATE
+ trigger returns the old tuple as-is, and it is not the last such
+ trigger (Thomas Munro)
+
+
+
+
+
+ Provide a relevant error context line when an error occurs while
+ setting GUC parameters during parallel worker startup (Thomas Munro)
+
+
+
+
+
+ In serializable mode, ensure that row-level predicate locks are
+ acquired on the correct version of the row (Thomas Munro, Heikki
+ Linnakangas)
+
+
+ If the visible version of the row is HOT-updated, the lock might be
+ taken on its now-dead predecessor, resulting in subtle failures to
+ guarantee serialization.
+
+
+
+
+
+ Ensure that fsync() is applied only to files
+ that are opened read/write (Andres Freund, Michael Paquier)
+
+
+ Some code paths tried to do this after opening a file read-only,
+ but on some platforms that causes bad file descriptor
+ or similar errors.
+
+
+
+
+
+ Allow encoding conversion to succeed on longer strings than before
+ (Álvaro Herrera, Tom Lane)
+
+
+ Previously, there was a hard limit of 0.25GB on the input string,
+ but now it will work as long as the converted output is not over 1GB.
+
+
+
+
+
+ Avoid an unnecessary catalog lookup during heap page pruning
+ (Thomas Munro)
+
+
+ It's no longer necessary to check for unlogged indexes here, and the
+ check caused significant performance problems in some workloads.
+ There was also at least a theoretical possibility of deadlock.
+
+
+
+
+
+ Avoid creating unnecessarily-bulky tuple stores for window functions
+ (Andrew Gierth)
+
+
+ In some cases the tuple storage would include all columns of the
+ source table(s), not just the ones that are needed by the query.
+
+
+
+
+
+ Allow repalloc() to give back space when a
+ large chunk is reduced in size (Tom Lane)
+
+
+
+
+
+ Ensure that temporary WAL and history files are removed at the end
+ of archive recovery (Sawada Masahiko)
+
+
+
+
+
+ Avoid failure in archive recovery
+ if recovery_min_apply_delay is enabled
+ (Fujii Masao)
+
+
+ recovery_min_apply_delay is not typically used in
+ this configuration, but it should work.
+
+
+
+
+
+ Fix logical replication failure when publisher and subscriber have
+ different ideas about a table's replica identity columns
+ (Jehan-Guillaume de Rorthais, Peter Eisentraut)
+
+
+ Declaring a column as part of the replica identity on the
+ subscriber, when it does not exist at all on the publisher, led
+ to negative bitmapset member not allowed
errors.
+
+
+
+
+
+ Avoid unwanted delay during shutdown of a logical replication
+ walsender (Craig Ringer, Álvaro Herrera)
+
+
+
+
+
+ Fix timeout handling in logical replication walreceiver processes
+ (Julien Rouhaud)
+
+
+ Erroneous logic prevented wal_receiver_timeout
+ from working in logical replication deployments.
+
+
+
+
+
+ Correctly time-stamp replication messages for logical
+ decoding (Jeff Janes)
+
+
+ This oversight resulted, for example,
+ in pg_stat_subscription.last_msg_send_time
+ usually reading as NULL.
+
+
+
+
+
+ In logical decoding, ensure that sub-transactions are correctly
+ accounted for when reconstructing a snapshot (Masahiko Sawada)
+
+
+ This error leads to assertion failures; it's unclear whether any
+ bad effects exist in production builds.
+
+
+
+
+
+ Fix race condition during backend exit, when the backend process has
+ previously waited for synchronous replication to occur (Dongming Liu)
+
+
+
+
+
+ Fix ALTER SYSTEM to cope with duplicate entries
+ in postgresql.auto.conf (Ian Barwick)
+
+
+ ALTER SYSTEM itself will not generate such a state,
+ but external tools that modify postgresql.auto.conf
+ could do so. Duplicate entries for the target variable will now be
+ removed, and then the new setting (if any) will be appended at the end.
+
+
+
+
+
+ Reject include directives with empty file names in configuration
+ files, and report include-file recursion more clearly
+ (Ian Barwick, Tom Lane)
+
+
+
+
+
+ Avoid logging complaints about abandoned connections when using PAM
+ authentication (Tom Lane)
+
+
+ libpq-based clients will typically make two connection attempts when
+ a password is required, since they don't prompt their user for a
+ password until their first connection attempt fails. Therefore the
+ server is coded not to generate useless log spam when a client
+ closes the connection upon being asked for a password. However,
+ the PAM authentication code hadn't gotten that memo, and would
+ generate several messages about a phantom authentication failure.
+
+
+
+
+
+ Fix some cases where an incomplete date specification is not
+ detected in time with time zone input (Alexander Lakhin)
+
+
+ If a time zone with a time-varying UTC offset is specified, then a
+ date must be as well, so that the offset can be resolved. Depending
+ on the syntax used, this check was not enforced in some cases,
+ allowing bogus output to be produced.
+
+
+
+
+
+ Fix misbehavior of bitshiftright() (Tom Lane)
+
+
+ The bitstring right shift operator failed to zero out padding space
+ that exists in the last byte of the result when the bitstring length
+ is not a multiple of 8. While invisible to most operations, any
+ nonzero bits there would result in unexpected comparison behavior,
+ since bitstring comparisons don't bother to ignore the extra bits,
+ expecting them to always be zero.
+
+
+ If you have inconsistent data as a result of saving the output
+ of bitshiftright() in a table, it's possible to
+ fix it with something like
+UPDATE mytab SET bitcol = ~(~bitcol) WHERE bitcol != ~(~bitcol);
+
+
+
+
+
+
+ Avoid crash when selecting a namespace node
+ in XMLTABLE (Chapman Flack)
+
+
+
+
+
+ Fix detection of edge-case integer overflow in interval
+ multiplication (Yuya Watari)
+
+
+
+
+
+ Fix memory leaks
+ in lower(), upper(),
+ and initcap() functions when using ICU
+ collations (Konstantin Knizhnik)
+
+
+
+
+
+ Avoid crashes if ispell text search dictionaries
+ contain wrong affix data (Arthur Zakirov)
+
+
+
+
+
+ Fix incorrect compression logic for GIN posting lists
+ (Heikki Linnakangas)
+
+
+ A GIN posting list item can require 7 bytes if the distance between
+ adjacent indexed TIDs exceeds 16TB. One step in the logic was out
+ of sync with that, and might try to write the value into a 6-byte
+ buffer. In principle this could cause a stack overrun, but on most
+ architectures it's likely that the next byte would be unused
+ alignment padding, making the bug harmless. In any case the bug
+ would be very difficult to hit.
+
+
+
+
+
+ Fix handling of infinity, NaN, and NULL values in KNN-GiST
+ (Alexander Korotkov)
+
+
+ The query's output order could be wrong (different from a plain
+ sort's result) if some distances computed for non-null column values
+ are infinity or NaN.
+
+
+
+
+
+ Fix handling of searches for NULL in KNN-SP-GiST (Nikita Glukhov)
+
+
+
+
+
+ On Windows, recognize additional spellings of the Norwegian
+ (Bokmål) locale name (Tom Lane)
+
+
+
+
+
+ Avoid compile failure if an ECPG client
+ includes ecpglib.h while
+ having ENABLE_NLS defined (Tom Lane)
+
+
+ This risk was created by a misplaced
+ declaration: ecpg_gettext() should not be
+ visible to client code.
+
+
+
+
+
+ In
psql, resynchronize internal state
+ about the server after an unexpected connection loss and successful
+ reconnection (Peter Billen, Tom Lane)
+
+
+ Ordinarily this is unnecessary since the state would be the same
+ anyway. But it can matter in corner cases, such as where the
+ connection might lead to one of several servers. This change
+ causes
psql to re-issue any interactive
+ messages that it would have issued at startup, for example about
+ whether SSL is in use.
+
+
+
+
+
+ Avoid platform-specific null pointer dereference
+ in
psql (Quentin Rameau)
+
+
+
+
+
+ In
pg_dump, ensure stable output order
+ for similarly-named triggers and row-level-security policy objects
+ (Benjie Gillam)
+
+
+ Previously, if two triggers on different tables had the same names,
+ they would be sorted in OID-based order, which is less desirable
+ than sorting them by table name. Likewise for RLS policies.
+
+
+
+
+
+ Fix
pg_dump to work again with pre-8.3
+ source servers (Tom Lane)
+
+
+ A previous fix caused
pg_dump to always
+ try to query pg_opfamily, but that catalog
+ doesn't exist before version 8.3.
+
+
+
+
+
+ as meaning output to stdout
+ (Álvaro Herrera)
+
+
+ This synchronizes
pg_restore's behavior
+ with some other applications, and in particular makes pre-v12 branches
+ act similarly to version 12's
pg_restore,
+ simplifying creation of dump/restore scripts that work across
+ multiple
PostgreSQL versions. Before this
+ change,
pg_restore interpreted such a
+ switch as meaning output to a file
+ named -, but few people would want that.
+
+
+
+
+
+ Improve
pg_upgrade's checks for the use
+ of a data type that has changed representation, such
+ as line (Tomas Vondra)
+
+
+ The previous coding could be fooled by cases where the data type of
+ interest underlies a stored column of a domain or composite type.
+
+
+
+
+
+ Detect file read errors
+ during
pg_basebackup (Jeevan Chalke)
+
+
+
+
+
+ In
pg_basebackup, don't fsync output files
+ until the end of backup (Michael Paquier)
+
+
+ The previous coding could result in timeout failures if fsync was slow.
+
+
+
+
+
+ In
pg_rewind with an online source
+ cluster, disable timeouts, much
+ as
pg_dump does (Alexander Kukushkin)
+
+
+
+
+
+ Fix failure in
pg_waldump with
+ the option, when a continuation WAL record ends
+ exactly at a page boundary (Andrey Lepikhov)
+
+
+
+
+
+ include the newitemoff field in btree page split
+ records (Peter Geoghegan)
+
+
+
+
+
+ the option, avoid emitting extra
+ newlines for WAL records involving full-page writes (Andres Freund)
+
+
+
+
+
+ Fix small memory leak in
pg_waldump+ (Andres Freund)
+
+
+
+
+
+ high option to handle running out of file
+ descriptors better (Michael Paquier)
+
+
+
+
+
+ Fix contrib/amcheck to skip unlogged indexes
+ during hot standby (Andrey Borodin, Peter Geoghegan)
+
+
+ An unlogged index won't necessarily contain valid data in this
+ context, so don't try to check it.
+
+
+
+
+
+ Fix contrib/intarray's GiST opclasses to not
+ fail for empty arrays with <@ (Tom Lane)
+
+
+ A clause like array_column
+ <@ constant_array is
+ considered indexable, but the index search may not find empty array
+ values; of course, such entries should trivially match the search.
+
+
+ The only practical back-patchable fix for this requires
+ making <@ index searches scan the whole index,
+ which is what this patch does. This is unfortunate: it means that
+ the query performance is likely worse than a plain sequential scan
+ would be.
+
+
+ Applications whose performance is adversely impacted by this change
+ have a couple of options. They could switch to a GIN index, which
+ doesn't have this bug, or they could replace
+ array_column
+ <@ constant_array
+ with array_column
+ <@ constant_array
+ AND array_column
+ && constant_array.
+ 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.
+
+
+
+
+
+ Fix
configure's test for presence of
+ libperl so that it works on recent Red Hat releases (Tom Lane)
+
+
+ Previously, it could fail if the user sets CFLAGS
+ to -O0.
+
+
+
+
+
+ Ensure correct code generation for spinlocks on PowerPC (Noah Misch)
+
+
+ The previous spinlock coding allowed the compiler to select register
+ zero for use with an assembly instruction that does not accept that
+ register, causing a build failure. We have seen only one long-ago
+ report that matches this bug, but it could cause problems for people
+ trying to build modified
PostgreSQL code
+ or use atypical compiler options.
+
+
+
+
+
+ On PowerPC, avoid depending on the xlc
+ compiler's __fetch_and_add() function
+ (Noah Misch)
+
+
+ xlc 13 and newer interpret this function in a way incompatible with
+ our usage, resulting in an unusable build
+ of
PostgreSQL. Fix by using custom
+ assembly code instead.
+
+
+
+
+
+ On AIX, don't use the compiler option
+ (Noah Misch)
+
+
+ This avoids an internal compiler error with xlc v16.1.0, with little
+ consequence other than changing the format of compiler error messages.
+
+
+
+
+
+ Fix MSVC build process to cope with spaces in the file path of
+ OpenSSL (Andrew Dunstan)
+
+
+
+
+
+ Update time zone data files to
tzdata+ release 2019c for DST law changes in Fiji and Norfolk Island, plus
+ historical corrections for Alberta, Austria, Belgium, British
+ Columbia, Cambodia, Hong Kong, Indiana (Perry County), Kaliningrad,
+ Kentucky, Michigan, Norfolk Island, South Korea, and Turkey.
