+ Release 9.2.21
+
+
+ Release Date
+ 2017-05-11
+
+
+
+ This release contains a variety of fixes from 9.2.20.
+ For information about new features in the 9.2 major release, see
+ .
+
+
+
+ The PostgreSQL> community will stop releasing updates
+ for the 9.2.X release series in September 2017.
+ Users are encouraged to update to a newer release branch soon.
+
+
+
+ Migration to Version 9.2.21
+
+
+ A dump/restore is not required for those running 9.2.X.
+
+
+
+ However, if you are upgrading from a version earlier than 9.2.20,
+ see .
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Fix possible corruption of init forks> of unlogged indexes
+ (Robert Haas, Michael Paquier)
+
+
+
+ This could result in an unlogged index being set to an invalid state
+ after a crash and restart. Such a problem would persist until the
+ index was dropped and rebuilt.
+
+
+
+
+
+ Fix incorrect reconstruction of pg_subtrans> entries
+ when a standby server replays a prepared but uncommitted two-phase
+ transaction (Tom Lane)
+
+
+
+ In most cases this turned out to have no visible ill effects, but in
+ corner cases it could result in circular references
+ in pg_subtrans>, potentially causing infinite loops
+ in queries that examine rows modified by the two-phase transaction.
+
+
+
+
+
+ Ensure parsing of queries in extension scripts sees the results of
+ immediately-preceding DDL (Julien Rouhaud, Tom Lane)
+
+
+
+ Due to lack of a cache flush step between commands in an extension
+ script file, non-utility queries might not see the effects of an
+ immediately preceding catalog change, such as ALTER TABLE
+ ... RENAME>.
+
+
+
+
+
+ Skip tablespace privilege checks when ALTER TABLE ... ALTER
+ COLUMN TYPE> rebuilds an existing index (Noah Misch)
+
+
+
+ The command failed if the calling user did not currently have
+ CREATE> privilege for the tablespace containing the index.
+ That behavior seems unhelpful, so skip the check, allowing the
+ index to be rebuilt where it is.
+
+
+
+
+
+ Fix ALTER TABLE ... VALIDATE CONSTRAINT> to not recurse
+ to child tables when the constraint is marked NO INHERIT>
+ (Amit Langote)
+
+
+
+ This fix prevents unwanted constraint does not exist> failures
+ when no matching constraint is present in the child tables.
+
+
+
+
+
+ Fix VACUUM> to account properly for pages that could not
+ be scanned due to conflicting page pins (Andrew Gierth)
+
+
+
+ This tended to lead to underestimation of the number of tuples in
+ the table. In the worst case of a small heavily-contended
+ table, VACUUM> could incorrectly report that the table
+ contained no tuples, leading to very bad planning choices.
+
+
+
+
+
+ Ensure that bulk-tuple-transfer loops within a hash join are
+ interruptible by query cancel requests (Tom Lane, Thomas Munro)
+
+
+
+
+
+ Fix cursor_to_xml()> to produce valid output
+ with tableforest> = false
+ (Thomas Munro, Peter Eisentraut)
+
+
+
+ Previously it failed to produce a wrapping <table>>
+ element.
+
+
+
+
+
+ Improve performance of pg_timezone_names> view
+ (Tom Lane, David Rowley)
+
+
+
+
+
+ Fix sloppy handling of corner-case errors from lseek()>
+ and close()> (Tom Lane)
+
+
+
+ Neither of these system calls are likely to fail in typical situations,
+ but if they did, fd.c> could get quite confused.
+
+
+
+
+
+ Fix incorrect check for whether postmaster is running as a Windows
+ service (Michael Paquier)
+
+
+
+ This could result in attempting to write to the event log when that
+ isn't accessible, so that no logging happens at all.
+
+
+
+
+
+ Fix ecpg> to support COMMIT PREPARED>
+ and ROLLBACK PREPARED> (Masahiko Sawada)
+
+
+
+
+
+ Fix a double-free error when processing dollar-quoted string literals
+ in ecpg> (Michael Meskes)
+
+
+
+
+
+ In pg_dump>, fix incorrect schema and owner marking for
+ comments and security labels of some types of database objects
+ (Giuseppe Broccolo, Tom Lane)
+
+
+
+ In simple cases this caused no ill effects; but for example, a
+ schema-selective restore might omit comments it should include, because
+ they were not marked as belonging to the schema of their associated
+ object.
+
+
+
+
+
+ Avoid emitting an invalid list file in pg_restore -l>
+ when SQL object names contain newlines (Tom Lane)
+
+
+
+ Replace newlines by spaces, which is sufficient to make the output
+ valid for pg_restore -L>'s purposes.
+
+
+
+
+
+ Fix pg_upgrade> to transfer comments and security labels
+ attached to large objects> (blobs) (Stephen Frost)
+
+
+
+ Previously, blobs were correctly transferred to the new database, but
+ any comments or security labels attached to them were lost.
+
+
+
+
+
+ Improve error handling
+ in contrib/adminpack>'s pg_file_write()>
+ function (Noah Misch)
+
+
+
+ Notably, it failed to detect errors reported
+ by fclose()>.
+
+
+
+
+
+ In contrib/dblink>, avoid leaking the previous unnamed
+ connection when establishing a new unnamed connection (Joe Conway)
+
+
+
+
+
+ Support OpenSSL 1.1.0 (Heikki Linnakangas, Andreas Karlsson, Tom Lane)
+
+
+
+ This is a back-patch of work previously done in newer branches;
+ it's needed since many platforms are adopting newer OpenSSL versions.
+
+
+
+
+
+ Support Tcl 8.6 in MSVC builds (Álvaro Herrera)
+
+
+
+
+
+ Sync our copy of the timezone library with IANA release tzcode2017b
+ (Tom Lane)
+
+
+
+ This fixes a bug affecting some DST transitions in January 2038.
+
+
+
+
+
+ Update time zone data files to tzdata> release 2017b
+ for DST law changes in Chile, Haiti, and Mongolia, plus historical
+ corrections for Ecuador, Kazakhstan, Liberia, and Spain.
+ Switch to numeric abbreviations for numerous time zones in South
+ America, the Pacific and Indian oceans, and some Asian and Middle
+ Eastern countries.
+
+
+
+ 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.
+
+
+
+
+
+ Use correct daylight-savings rules for POSIX-style time zone names
+ in MSVC builds (David Rowley)
+
+
+
+ The Microsoft MSVC build scripts neglected to install
+ the posixrules> file in the timezone directory tree.
+ This resulted in the timezone code falling back to its built-in
+ rule about what DST behavior to assume for a POSIX-style time zone
+ name. For historical reasons that still corresponds to the DST rules
+ the USA was using before 2007 (i.e., change on first Sunday in April
+ and last Sunday in October). With this fix, a POSIX-style zone name
+ will use the current and historical DST transition dates of
+ the US/Eastern> zone. If you don't want that, remove
+ the posixrules> file, or replace it with a copy of some
+ other zone file (see ). Note that
+ due to caching, you may need to restart the server to get such changes
+ to take effect.
