+ .
+
+
+
+ Migration to Version 9.4.5

+
+
+
+ Changes
+
+
+
+
+
+
+
+ Fix subtransaction cleanup after a portal (cursor) belonging to an
+ outer subtransaction fails (Tom Lane and Michael Paquier)
+
+
+
+ A function executed in an outer-subtransaction cursor could cause an
+ assertion failure or crash by referencing a relation created within an
+ inner subtransaction.
+
+
+
+
+
+
+
+ Fix possible deadlock during WAL insertion
+ when commit_delay is set (Heikki Linnakangas)
+
+
+
+
+
+
+
+ Ensure all relations referred to by an updatable view are properly
+ locked during an update statement (Dean Rasheed)
+
+
+
+
+
+
+
+ Fix insertion of relations into the relation cache init file
+ (Tom Lane)
+
+
+
+ An oversight in a patch in the most recent minor releases
+ caused pg_trigger_tgrelid_tgname_index to be omitted
+ from the init file. Subsequent sessions detected this, then deemed the
+ init file to be broken and silently ignored it, resulting in a
+ significant degradation in session startup time. In addition to fixing
+ the bug, install some guards so that any similar future mistake will be
+ more obvious.
+
+
+
+
+
+
+
+ Avoid O(N^2) behavior when inserting many tuples into a SPI query
+ result (Neil Conway)
+
+
+
+
+
+
+
+ Improve LISTEN startup time when there are many unread
+ notifications (Matt Newell)
+
+
+
+
+
+
+
+ Fix performance problem when a session alters large numbers of foreign
+ key constraints (Jan Wieck, Tom Lane)
+
+
+
+ This was seen primarily when restoring pg_dump output
+ for databases with many thousands of tables.
+
+
+
+
+
+
+
+ Back-patch 9.3-era addition of per-resource-owner lock caches
+ (Jeff Janes)
+
+
+
+ This substantially improves performance when pg_dump
+ tries to dump a large number of tables.
+
+
+
+
+
+
+
+ Disable SSL renegotiation by default (Michael Paquier, Andres Freund)
+
+
+
+ While use of SSL renegotiation is a good idea in theory, we have seen
+ too many bugs in practice, both in the underlying OpenSSL library and
+ in our usage of it. Renegotiation will be removed entirely in 9.5 and
+ later. In the older branches, just change the default value
+ of ssl_renegotiation_limit to zero (disabled).
+
+
+
+
+
+
+
+ Lower the minimum values of the *_freeze_max_age parameters
+ (Andres Freund)
+
+
+
+ This is mainly to make tests of related behavior less time-consuming,
+ but it may also be of value for installations with limited disk space.
+
+
+
+
+
+
+
+ Limit the maximum value of wal_buffers to 2GB to avoid
+ server crashes (Josh Berkus)
+
+
+
+
+
+
+
+ Avoid logging complaints when a parameter that can only be set at
+ server start appears multiple times in postgresql.conf,
+ and fix counting of line numbers after an include_dir
+ directive (Tom Lane)
+
+
+
+
+
+
+
+ Fix rare internal overflow in multiplication of numeric values
+ (Dean Rasheed)
+
+
+
+
+
+
+
+ Fix handling of DOW and DOY in datetime input
+ (Greg Stark)
+
+
+
+ These tokens aren't meant to be used in datetime values, but previously
+ they resulted in opaque internal error messages rather
+ than invalid input syntax.
+
+
+
+
+
+
+
+ Add more query-cancel checks to regular expression matching (Tom Lane)
+
+
+
+
+
+
+
+ Add recursion depth protections to regular expression, SIMILAR
+ TO, and LIKE matching (Tom Lane)
+
+
+
+ Suitable search patterns and a low stack depth limit could lead to
+ stack-overrun crashes.
+
+
+
+
+
+
+
+ Fix potential infinite loop in regular expression execution (Tom Lane)
+
+
+
+ A search pattern that can apparently match a zero-length string, but
+ actually doesn't match because of a back reference, could lead to an
+ infinite loop.
+
+
+
+
+
+
+
+ In regular expression execution, correctly record match data for
+ capturing parentheses within a quantifier even when the match is
+ zero-length (Tom Lane)
+
+
+
+
+
+
+
+ Fix low-memory failures in regular expression compilation
+ (Andreas Seltenreich)
+
+
+
+
+
+
+
+ Fix low-probability memory leak during regular expression execution
+ (Tom Lane)
+
+
+
+
+
+
+
+ Fix rare low-memory failure in lock cleanup during transaction abort
+ (Tom Lane)
+
+
+
+
+
+
+
+ Fix unexpected out-of-memory situation during sort errors
+ when using tuplestores with small work_mem settings (Tom
+ Lane)
+
+
+
+
+
+
+
+ Fix very-low-probability stack overrun in qsort (Tom Lane)
+
+
+
+
+
+
+
+ Fix assorted planner bugs (Tom Lane)
+
+
+
+ These mistakes could lead to incorrect query plans that would give wrong
+ answers, or to assertion failures in assert-enabled builds, or to odd
+ planner errors such as could not devise a query plan for the
+ given query, could not find pathkey item to
+ sort, plan should not reference subplan's variable,
+ or failed to assign all NestLoopParams to plan nodes.
+ Thanks are due to Andreas Seltenreich and Piotr Stefaniak for fuzz
+ testing that exposed these problems.
+
+
+
+
+
+
+
+ Improve planner's performance for UPDATE/DELETE
+ on large inheritance sets (Tom Lane, Dean Rasheed)
+
+
+
+
+
+
+
+ Use fuzzy path cost tiebreaking rule in all supported branches (Tom Lane)
+
+
+
+ This change is meant to avoid platform-specific behavior when
+ alternative plan choices have effectively-identical estimated costs.
+
+
+
+
+
+
+
+ Ensure standby promotion trigger files are removed at postmaster
+ startup (Michael Paquier, Fujii Masao)
+
+
+
+ This prevents unwanted promotion from occurring if these files appear
+ in a database backup that is used to initialize a new standby server.
+
+
+
+
+
+
+
+ During postmaster shutdown, ensure that per-socket lock files are
+ removed and listen sockets are closed before we remove
+ the postmaster.pid file (Tom Lane)
+
+
+
+ This avoids race-condition failures if an external script attempts to
+ start a new postmaster as soon as pg_ctl stop returns.
+
+
+
+
+
+
+
+ Ensure that the postmaster does not exit until all its child processes
+ are gone, even in an immediate shutdown (Tom Lane)
+
+
+
+ Like the previous item, this avoids possible race conditions against a
+ subsequently-started postmaster.
+
+
+
+
+
+
+
+ Fix postmaster's handling of a startup-process crash during crash
+ recovery (Tom Lane)
+
+
+
+ If, during a crash recovery cycle, the startup process crashes without
+ having restored database consistency, we'd try to launch a new startup
+ process, which typically would just crash again, leading to an infinite
+ loop.
+
+
+
+
+
+
+
+ Make emergency autovacuuming for multixact wraparound more robust
+ (Andres Freund)
+
+
+
+
+
+
+
+ Do not print a WARNING when an autovacuum worker is already
+ gone when we attempt to signal it, and reduce log verbosity for such
+ signals (Tom Lane)
+
+
+
+
+
+
+
+ Prevent autovacuum launcher from sleeping unduly long if the server
+ clock is moved backwards a large amount (Álvaro Herrera)
+
+
+
+
+
+
+
+ Ensure that cleanup of a GIN index's pending-insertions list is
+ interruptable by cancel requests (Jeff Janes)
+
+
+
+
+
+
+
+ Allow all-zeroes pages in GIN indexes to be reused (Heikki Linnakangas)
+
+
+
+ Such a page might be left behind after a crash.
+
+
+
+
+
+
+
+ Fix handling of all-zeroes pages in SP-GiST indexes (Heikki
+ Linnakangas)
+
+
+
+ VACUUM attempted to recycle such pages, but did so in a
+ way that wasn't crash-safe.
+
+
+
+
+
+
+
+ Fix off-by-one error that led to otherwise-harmless warnings
+ about apparent wraparound in subtrans/multixact truncation
+ (Thomas Munro)
+
+
+
+
+
+
+
+ Fix misreporting of CONTINUE and MOVE statement
+ types in PL/pgSQL's error context messages
+ (Pavel Stehule and Tom Lane)
+
+
+
+
+
+
+
+ Fix PL/Perl to handle non-ASCII error
+ message texts correctly (Alex Hunsaker)
+
+
+
+
+
+
+
+ Fix PL/Python crash when returning the string
+ representation of a record result (Tom Lane)
+
+
+
+
+
+
+
+ Fix some places in PL/Tcl that neglected to check for
+ failure of malloc() calls (Michael Paquier, Álvaro
+ Herrera)
+
+
+
+
+
+
+
+ In contrib/isn, fix output of ISBN-13 numbers that begin
+ with 979 (Fabien Coelho)
+
+
+
+ EANs beginning with 979 (but not 9790) are considered ISBNs, but they
+ must be printed in the new 13-digit format, not the 10-digit format.
+
+
+
+
+
+
+
+ Improve contrib/postgres_fdw's handling of
+ collation-related decisions (Tom Lane)
+
+
+
+ The main user-visible effect is expected to be that comparisons
+ involving varchar columns will be sent to the remote server
+ for execution in more cases than before.
+
+
+
+
+
+
+
+ Fix contrib/sepgsql's handling of SELECT INTO
+ statements (Kohei KaiGai)
+
+
+
+
+
+
+
+ Improve libpq's handling of out-of-memory conditions
+ (Michael Paquier, Heikki Linnakangas)
+
+
+
+
+
+
+
+ Fix memory leaks and missing out-of-memory checks
+ in ecpg (Michael Paquier)
+
+
+
+
+
+
+
+ Fix psql's code for locale-aware formatting of numeric
+ output (Tom Lane)
+
+
+
+ The formatting code invoked by \pset numericlocale on
+ did the wrong thing for some uncommon cases such as numbers with an
+ exponent but no decimal point. It could also mangle already-localized
+ output from the money data type.
+
+
+
+
+
+
+
+ Prevent crash in psql's \c command when
+ there is no current connection (Noah Misch)
+
+
+
+
+
+
+
+ Make pg_dump handle inherited NOT VALID
+ check constraints correctly (Tom Lane)
+
+
+
+
+
+
+
+ Fix selection of default zlib compression level
+ in pg_dump's directory output format (Andrew Dunstan)
+
+
+
+
+
+
+
+ Ensure that temporary files created during a pg_dump
+ run with tar-format output are not world-readable (Michael
+ Paquier)
+
+
+
+
+
+
+
+ Fix pg_dump and pg_upgrade to support
+ cases where the postgres or template1 database
+ is in a non-default tablespace (Marti Raudsepp, Bruce Momjian)
+
+
+
+
+
+
+
+ Fix pg_dump to handle object privileges sanely when
+ dumping from a server too old to have a particular privilege type
+ (Tom Lane)
+
+
+
+ When dumping data types from pre-9.2 servers, and when dumping
+ functions or procedural languages from pre-7.3
+ servers, pg_dump would
+ produce GRANT/REVOKE commands that revoked the
+ owner's grantable privileges and instead granted all privileges
+ to PUBLIC. Since the privileges involved are
+ just USAGE and EXECUTE, this isn't a security
+ problem, but it's certainly a surprising representation of the older
+ systems' behavior. Fix it to leave the default privilege state alone
+ in these cases.
+
+
+
+
+
+
+
+ Fix pg_dump to dump shell types (Tom Lane)
+
+
+
+ Shell types (that is, not-yet-fully-defined types) aren't useful for
+ much, but nonetheless pg_dump should dump them.
+
+
+
+
+
+
+
+ Fix assorted minor memory leaks in pg_dump and other
+ client-side programs (Michael Paquier)
+
+
+
+
+
+
+
+ Fix pgbench's progress-report behavior when a query,
+ or pgbench itself, gets stuck (Fabien Coelho)
+
+
+
+
+
+
+
+ Fix spinlock assembly code for Alpha hardware (Tom Lane)
+
+
+
+
+
+
+
+ Fix spinlock assembly code for PPC hardware to be compatible
+ with AIX's native assembler (Tom Lane)
+
+
+
+ Building with gcc didn't work if gcc
+ had been configured to use the native assembler, which is becoming more
+ common.
+
+
+
+
+
+
+
+ On AIX, test the -qlonglong compiler option
+ rather than just assuming it's safe to use (Noah Misch)
+
+
+
+
+
+
+
+ On AIX, use -Wl,-brtllib link option to allow
+ symbols to be resolved at runtime (Noah Misch)
+
+
+
+ Perl relies on this ability in 5.8.0 and later.
+
+
+
+
+
+
+
+ Avoid use of inline functions when compiling with
+ 32-bit xlc, due to compiler bugs (Noah Misch)
+
+
+
+
+
+
+
+ Use librt for sched_yield() when necessary,
+ which it is on some Solaris versions (Oskari Saarenmaa)
+
+
+
+
+
+
+
+ Translate encoding UHC as Windows code page 949
+ (Noah Misch)
+
+
+
+ This fixes presentation of non-ASCII log messages from processes that
+ are not attached to any particular database, such as the postmaster.
+
+
+
+
+
+
+
+ On Windows, avoid failure when doing encoding conversion to UTF16
+ outside a transaction, such as for log messages (Noah Misch)
+
+
+
+
+
+
+
+ Fix postmaster startup failure due to not
+ copying setlocale()'s return value (Noah Misch)
+
+
+
+ This has been reported on Windows systems with the ANSI code page set
+ to CP936 (Chinese (Simplified, PRC)), and may occur with
+ other multibyte code pages.
+
+
+
+
+
+
+
+ Fix Windows install.bat script to handle target directory
+ names that contain spaces (Heikki Linnakangas)
+
+
+
+
+
+
+
+ Make the numeric form of the PostgreSQL version number
+ (e.g., 90405) readily available to extension Makefiles,
+ as a variable named VERSION_NUM (Michael Paquier)
+
+
+
+
+
+
+
+ Update time zone data files to tzdata release 2015g for
+ DST law changes in Cayman Islands, Fiji, Moldova, Morocco, Norfolk
+ Island, North Korea, Turkey, and Uruguay. There is a new zone name
+ America/Fort_Nelson for the Canadian Northern Rockies.
