+ Release 9.2.20
+
+
+ Release Date
+ 2017-02-09
+
+
+
+ This release contains a variety of fixes from 9.2.19.
+ For information about new features in the 9.2 major release, see
+ .
+
+
+
+ Migration to Version 9.2.20
+
+
+ A dump/restore is not required for those running 9.2.X.
+
+
+
+ However, if your installation has been affected by the bug described in
+ the first changelog entry below, then after updating you may need
+ to take action to repair corrupted indexes.
+
+
+
+ Also, if you are upgrading from a version earlier than 9.2.11,
+ see .
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Fix a race condition that could cause indexes built
+ with CREATE INDEX CONCURRENTLY to be corrupt
+ (Pavan Deolasee, Tom Lane)
+
+
+
+ If CREATE INDEX CONCURRENTLY was used to build an index
+ that depends on a column not previously indexed, then rows inserted
+ or updated by transactions that ran concurrently with
+ the CREATE INDEX command could have received incorrect
+ index entries. If you suspect this may have happened, the most
+ reliable solution is to rebuild affected indexes after installing
+ this update.
+
+
+
+
+
+ Unconditionally WAL-log creation of the init fork for an
+ unlogged table (Michael Paquier)
+
+
+
+ Previously, this was skipped when
+ = minimal, but actually it's necessary even in that case
+ to ensure that the unlogged table is properly reset to empty after a
+ crash.
+
+
+
+
+
+
+ Fix WAL page header validation when re-reading segments (Takayuki
+ Tsunakawa, Amit Kapila)
+
+
+
+ In corner cases, a spurious out-of-sequence TLI error
+ could be reported during recovery.
+
+
+
+
+
+ If the stats collector dies during hot standby, restart it (Takayuki
+ Tsunakawa)
+
+
+
+
+
+ Check for interrupts while hot standby is waiting for a conflicting
+ query (Simon Riggs)
+
+
+
+
+
+ Avoid constantly respawning the autovacuum launcher in a corner case
+ (Amit Khandekar)
+
+
+
+ This fix avoids problems when autovacuum is nominally off and there
+ are some tables that require freezing, but all such tables are
+ already being processed by autovacuum workers.
+
+
+
+
+
+ Fix check for when an extension member object can be dropped (Tom Lane)
+
+
+
+ Extension upgrade scripts should be able to drop member objects,
+ but this was disallowed for serial-column sequences, and possibly
+ other cases.
+
+
+
+
+
+ Make sure ALTER TABLE preserves index tablespace
+ assignments when rebuilding indexes (Tom Lane, Michael Paquier)
+
+
+
+ Previously, non-default settings
+ of could result in broken
+ indexes.
+
+
+
+
+
+ Prevent dropping a foreign-key constraint if there are pending
+ trigger events for the referenced relation (Tom Lane)
+
+
+
+ This avoids could not find trigger NNN
+ or relation NNN has no triggers
errors.
+
+
+
+
+
+ Fix processing of OID column when a table with OIDs is associated to
+ a parent with OIDs via ALTER TABLE ... INHERIT (Amit
+ Langote)
+
+
+
+ The OID column should be treated the same as regular user columns in
+ this case, but it wasn't, leading to odd behavior in later
+ inheritance changes.
+
+
+
+
+
+ Check for serializability conflicts before reporting
+ constraint-violation failures (Thomas Munro)
+
+
+
+ When using serializable transaction isolation, it is desirable
+ that any error due to concurrent transactions should manifest
+ as a serialization failure, thereby cueing the application that
+ a retry might succeed. Unfortunately, this does not reliably
+ happen for duplicate-key failures caused by concurrent insertions.
+ This change ensures that such an error will be reported as a
+ serialization error if the application explicitly checked for
+ the presence of a conflicting key (and did not find it) earlier
+ in the transaction.
+
+
+
+
+
+ Ensure that column typmods are determined accurately for
+ multi-row VALUES constructs (Tom Lane)
+
+
+
+ This fixes problems occurring when the first value in a column has a
+ determinable typmod (e.g., length for a varchar value) but
+ later values don't share the same limit.
+
+
+
+
+
+ Throw error for an unfinished Unicode surrogate pair at the end of a
+ Unicode string (Tom Lane)
+
+
+
+ Normally, a Unicode surrogate leading character must be followed by a
+ Unicode surrogate trailing character, but the check for this was
+ missed if the leading character was the last character in a Unicode
+ string literal (U&'...') or Unicode identifier
+ (U&"...").
+
+
+
+
+
+ Ensure that a purely negative text search query, such
+ as !foo, matches empty tsvectors (Tom Dunstan)
+
+
+
+ Such matches were found by GIN index searches, but not by sequential
+ scans or GiST index searches.
+
+
+
+
+
+ Prevent crash when ts_rewrite() replaces a non-top-level
+ subtree with an empty query (Artur Zakirov)
+
+
+
+
+
+ Fix performance problems in ts_rewrite() (Tom Lane)
+
+
+
+
+
+ Fix ts_rewrite()'s handling of nested NOT operators
+ (Tom Lane)
+
+
+
+
+
+ Fix array_fill() to handle empty arrays properly (Tom Lane)
+
+
+
+
+
+ Fix one-byte buffer overrun in quote_literal_cstr()
+ (Heikki Linnakangas)
+
+
+
+ The overrun occurred only if the input consisted entirely of single
+ quotes and/or backslashes.
+
+
+
+
+
+ Prevent multiple calls of pg_start_backup()
+ and pg_stop_backup() from running concurrently (Michael
+ Paquier)
+
+
+
+ This avoids an assertion failure, and possibly worse things, if
+ someone tries to run these functions in parallel.
+
+
+
+
+
+ Avoid discarding interval-to-interval casts
+ that aren't really no-ops (Tom Lane)
+
+
+
+ In some cases, a cast that should result in zeroing out
+ low-order interval fields was mistakenly deemed to be a
+ no-op and discarded. An example is that casting from INTERVAL
+ MONTH to INTERVAL YEAR failed to clear the months field.
+
+
+
+
+
+ Fix pg_dump to dump user-defined casts and transforms
+ that use built-in functions (Stephen Frost)
+
+
+
+
+
+ Fix possible pg_basebackup failure on standby
+ server when including WAL files (Amit Kapila, Robert Haas)
+
+
+
+
+
+ Ensure that the Python exception objects we create for PL/Python are
+ properly reference-counted (Rafa de la Torre, Tom Lane)
+
+
+
+ This avoids failures if the objects are used after a Python garbage
+ collection cycle has occurred.
+
+
+
+
+
+ Fix PL/Tcl to support triggers on tables that have .tupno
+ as a column name (Tom Lane)
+
+
+
+ This matches the (previously undocumented) behavior of
+ PL/Tcl's spi_exec and spi_execp commands,
+ namely that a magic .tupno column is inserted only if
+ there isn't a real column named that.
+
+
+
+
+
+ Allow DOS-style line endings in ~/.pgpass files,
+ even on Unix (Vik Fearing)
+
+
+
+ This change simplifies use of the same password file across Unix and
+ Windows machines.
+
+
+
+
+
+ Fix one-byte buffer overrun if ecpg is given a file
+ name that ends with a dot (Takayuki Tsunakawa)
+
+
+
+
+
+ Fix psql's tab completion for ALTER DEFAULT
+ PRIVILEGES (Gilles Darold, Stephen Frost)
+
+
+
+
+
+ In psql, treat an empty or all-blank setting of
+ the PAGER environment variable as meaning no
+ pager (Tom Lane)
+
+
+
+ Previously, such a setting caused output intended for the pager to
+ vanish entirely.
+
+
+
+
+
+ Improve contrib/dblink's reporting of
+ low-level libpq errors, such as out-of-memory
+ (Joe Conway)
+
+
+
+
+
+ On Windows, ensure that environment variable changes are propagated
+ to DLLs built with debug options (Christian Ullrich)
+
+
+
+
+
+ Sync our copy of the timezone library with IANA release tzcode2016j
+ (Tom Lane)
+
+
+
+ This fixes various issues, most notably that timezone data
+ installation failed if the target directory didn't support hard
+ links.
+
+
+
+
+
+ Update time zone data files to tzdata release 2016j
+ for DST law changes in northern Cyprus (adding a new zone
+ Asia/Famagusta), Russia (adding a new zone Europe/Saratov), Tonga,
+ and Antarctica/Casey.
+ Historical corrections for Italy, Kazakhstan, Malta, and Palestine.
+ Switch to preferring numeric zone abbreviations for Tonga.
