+
+ Release 8.4.20
+
+
+ Release Date
+ 2014-02-20
+
+
+
+ This release contains a variety of fixes from 8.4.19.
+ For information about new features in the 8.4 major release, see
+ .
+
+
+
+ The PostgreSQL community will stop releasing updates
+ for the 8.4.X release series in July 2014.
+ Users are encouraged to update to a newer release branch soon.
+
+
+
+ Migration to Version 8.4.20
+
+
+ A dump/restore is not required for those running 8.4.X.
+
+
+
+ However, if you are upgrading from a version earlier than 8.4.19,
+ see .
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Fix possible mis-replay of WAL records when some segments of a
+ relation aren't full size (Greg Stark, Tom Lane)
+
+
+
+ The WAL update could be applied to the wrong page, potentially many
+ pages past where it should have been. Aside from corrupting data,
+ this error has been observed to result in significant bloat
+ of standby servers compared to their masters, due to updates being
+ applied far beyond where the end-of-file should have been. This
+ failure mode does not appear to be a significant risk during crash
+ recovery, only when initially synchronizing a standby created from a
+ base backup taken from a quickly-changing master.
+
+
+
+
+
+ Ensure that insertions into non-leaf GIN index pages write a full-page
+ WAL record when appropriate (Heikki Linnakangas)
+
+
+
+ The previous coding risked index corruption in the event of a
+ partial-page write during a system crash.
+
+
+
+
+
+ Fix race conditions during server process exit (Robert Haas)
+
+
+
+ Ensure that signal handlers don't attempt to use the
+ process's MyProc pointer after it's no longer valid.
+
+
+
+
+
+ Fix unsafe references to errno within error reporting
+ logic (Christian Kruse)
+
+
+
+ This would typically lead to odd behaviors such as missing or
+ inappropriate HINT fields.
+
+
+
+
+
+ Fix possible crashes from using ereport() too early
+ during server startup (Tom Lane)
+
+
+
+ The principal case we've seen in the field is a crash if the server
+ is started in a directory it doesn't have permission to read.
+
+
+
+
+
+ Clear retry flags properly in OpenSSL socket write
+ function (Alexander Kukushkin)
+
+
+
+ This omission could result in a server lockup after unexpected loss
+ of an SSL-encrypted connection.
+
+
+
+
+
+ Fix length checking for Unicode identifiers (U&"..."
+ syntax) containing escapes (Tom Lane)
+
+
+
+ A spurious truncation warning would be printed for such identifiers
+ if the escaped form of the identifier was too long, but the
+ identifier actually didn't need truncation after de-escaping.
+
+
+
+
+
+ Fix possible crash due to invalid plan for nested sub-selects, such
+ as WHERE (... x IN (SELECT ...) ...) IN (SELECT ...)
+ (Tom Lane)
+
+
+
+
+
+ Ensure that ANALYZE creates statistics for a table column
+ even when all the values in it are too wide (Tom Lane)
+
+
+
+ ANALYZE intentionally omits very wide values from its
+ histogram and most-common-values calculations, but it neglected to do
+ something sane in the case that all the sampled entries are too wide.
+
+
+
+
+
+ In ALTER TABLE ... SET TABLESPACE, allow the database's
+ default tablespace to be used without a permissions check
+ (Stephen Frost)
+
+
+
+ CREATE TABLE has always allowed such usage,
+ but ALTER TABLE didn't get the memo.
+
+
+
+
+
+ Fix cannot accept a set error when some arms of
+ a CASE return a set and others don't (Tom Lane)
+
+
+
+
+
+ Fix checks for all-zero client addresses in pgstat functions (Kevin
+ Grittner)
+
+
+
+
+
+ Fix possible misclassification of multibyte characters by the text
+ search parser (Tom Lane)
+
+
+
+ Non-ASCII characters could be misclassified when using C locale with
+ a multibyte encoding. On Cygwin, non-C locales could fail as well.
+
+
+
+
+
+ Fix possible misbehavior in plainto_tsquery()
+ (Heikki Linnakangas)
+
+
+
+ Use memmove() not memcpy() for copying
+ overlapping memory regions. There have been no field reports of
+ this actually causing trouble, but it's certainly risky.
+
+
+
+
+
+ Accept SHIFT_JIS as an encoding name for locale checking
+ purposes (Tatsuo Ishii)
+
+
+
+
+
+ Fix misbehavior of PQhost() on Windows (Fujii Masao)
+
+
+
+ It should return localhost if no host has been specified.
+
+
+
+
+
+ Improve error handling in libpq and psql
+ for failures during COPY TO STDOUT/FROM STDIN (Tom Lane)
+
+
+
+ In particular this fixes an infinite loop that could occur in 9.2 and
+ up if the server connection was lost during COPY FROM
+ STDIN. Variants of that scenario might be possible in older
+ versions, or with other client applications.
+
+
+
+
+
+ Fix misaligned descriptors in ecpg (MauMau)
+
+
+
+
+
+ In ecpg, handle lack of a hostname in the connection
+ parameters properly (Michael Meskes)
+
+
+
+
+
+ Fix performance regression in contrib/dblink connection
+ startup (Joe Conway)
+
+
+
+ Avoid an unnecessary round trip when client and server encodings match.
+
+
+
+
+
+ In contrib/isn, fix incorrect calculation of the check
+ digit for ISMN values (Fabien Coelho)
+
+
+
+
+
+ Ensure client-code-only installation procedure works as documented
+ (Peter Eisentraut)
+
+
+
+
+
+ In Mingw and Cygwin builds, install the libpq DLL
+ in the bin directory (Andrew Dunstan)
+
+
+
+ This duplicates what the MSVC build has long done. It should fix
+ problems with programs like psql failing to start
+ because they can't find the DLL.
+
+
+
+
+
+ Don't generate plain-text HISTORY
+ and src/test/regress/README files anymore (Tom Lane)
+
+
+
+ These text files duplicated the main HTML and PDF documentation
+ formats. The trouble involved in maintaining them greatly outweighs
+ the likely audience for plain-text format. Distribution tarballs
+ will still contain files by these names, but they'll just be stubs
+ directing the reader to consult the main documentation.
+ The plain-text INSTALL file will still be maintained, as
+ there is arguably a use-case for that.
+
+
+
+
+
+ Update time zone data files to tzdata release 2013i
+ for DST law changes in Jordan and historical changes in Cuba.
+
+
+
+ In addition, the zones Asia/Riyadh87,
+ Asia/Riyadh88, and Asia/Riyadh89 have been
+ removed, as they are no longer maintained by IANA, and never
+ represented actual civil timekeeping practice.

+ Fix possible mis-replay of WAL records when some segments of a
+ relation aren't full size (Greg Stark, Tom Lane)
+
+
+
+ The WAL update could be applied to the wrong page, potentially many
+ pages past where it should have been. Aside from corrupting data,
+ this error has been observed to result in significant bloat
+ of standby servers compared to their masters, due to updates being
+ applied far beyond where the end-of-file should have been. This
+ failure mode does not appear to be a significant risk during crash
+ recovery, only when initially synchronizing a standby created from a
+ base backup taken from a quickly-changing master.
+
+
+
+
+
+ Fix bug in determining when recovery has reached consistency
+ (Tomonari Katsumata, Heikki Linnakangas)
+
+
+
+ In some cases WAL replay would mistakenly conclude that the database
+ was already consistent at the start of replay, thus possibly allowing
+ hot-standby queries before the database was really consistent. Other
+ symptoms such as PANIC: WAL contains references to invalid
+ pages were also possible.
+
+
+
+
+
+ Fix improper locking of btree index pages while replaying
+ a VACUUM operation in hot-standby mode (Andres Freund,
+ Heikki Linnakangas, Tom Lane)
+
+
+
+ This error could result in PANIC: WAL contains references to
+ invalid pages failures.
+
+
+
+
+
+ Ensure that insertions into non-leaf GIN index pages write a full-page
+ WAL record when appropriate (Heikki Linnakangas)
+
+
+
+ The previous coding risked index corruption in the event of a
+ partial-page write during a system crash.
+
+
+
+
+
+ When pause_at_recovery_target
+ and recovery_target_inclusive are both set, ensure the
+ target record is applied before pausing, not after (Heikki
+ Linnakangas)
+
+
+
+
+
+ Fix race conditions during server process exit (Robert Haas)
+
+
+
+ Ensure that signal handlers don't attempt to use the
+ process's MyProc pointer after it's no longer valid.
+
+
+
+
+
+ Fix race conditions in walsender shutdown logic and walreceiver
+ SIGHUP signal handler (Tom Lane)
+
+
+
+
+
+ Fix unsafe references to errno within error reporting
+ logic (Christian Kruse)
+
+
+
+ This would typically lead to odd behaviors such as missing or
+ inappropriate HINT fields.
+
+
+
+
+
+ Fix possible crashes from using ereport() too early
+ during server startup (Tom Lane)
+
+
+
+ The principal case we've seen in the field is a crash if the server
+ is started in a directory it doesn't have permission to read.
+
+
+
+
+
+ Clear retry flags properly in OpenSSL socket write
+ function (Alexander Kukushkin)
+
+
+
+ This omission could result in a server lockup after unexpected loss
+ of an SSL-encrypted connection.
+
+
+
+
+
+ Fix length checking for Unicode identifiers (U&"..."
+ syntax) containing escapes (Tom Lane)
+
+
+
+ A spurious truncation warning would be printed for such identifiers
+ if the escaped form of the identifier was too long, but the
+ identifier actually didn't need truncation after de-escaping.
+
+
+
+
+
+ Allow keywords that are type names to be used in lists of roles
+ (Stephen Frost)
+
+
+
+ A previous patch allowed such keywords to be used without quoting
+ in places such as role identifiers; but it missed cases where a
+ list of role identifiers was permitted, such as DROP ROLE.
+
+
+
+
+
+ Fix parser crash for EXISTS(SELECT * FROM
+ zero_column_table) (Tom Lane)
+
+
+
+
+
+ Fix possible crash due to invalid plan for nested sub-selects, such
+ as WHERE (... x IN (SELECT ...) ...) IN (SELECT ...)
+ (Tom Lane)
+
+
+
+
+
+ Fix UPDATE/DELETE of an inherited target table
+ that has UNION ALL subqueries (Tom Lane)
+
+
+
+ Without this fix, UNION ALL subqueries aren't correctly
+ inserted into the update plans for inheritance child tables after the
+ first one, typically resulting in no update happening for those child
+ table(s).
+
+
+
+
+
+ Ensure that ANALYZE creates statistics for a table column
+ even when all the values in it are too wide (Tom Lane)
+
+
+
+ ANALYZE intentionally omits very wide values from its
+ histogram and most-common-values calculations, but it neglected to do
+ something sane in the case that all the sampled entries are too wide.
+
+
+
+
+
+ In ALTER TABLE ... SET TABLESPACE, allow the database's
+ default tablespace to be used without a permissions check
+ (Stephen Frost)
+
+
+
+ CREATE TABLE has always allowed such usage,
+ but ALTER TABLE didn't get the memo.
+
+
+
+
+
+ Fix cannot accept a set error when some arms of
+ a CASE return a set and others don't (Tom Lane)
+
+
+
+
+
+ Properly distinguish numbers from non-numbers when generating JSON
+ output (Andrew Dunstan)
+
+
+
+
+
+ Fix checks for all-zero client addresses in pgstat functions (Kevin
+ Grittner)
+
+
+
+
+
+ Fix possible misclassification of multibyte characters by the text
+ search parser (Tom Lane)
+
+
+
+ Non-ASCII characters could be misclassified when using C locale with
+ a multibyte encoding. On Cygwin, non-C locales could fail as well.
+
+
+
+
+
+ Fix possible misbehavior in plainto_tsquery()
+ (Heikki Linnakangas)
+
+
+
+ Use memmove() not memcpy() for copying
+ overlapping memory regions. There have been no field reports of
+ this actually causing trouble, but it's certainly risky.
+
+
+
+
+
+ Fix placement of permissions checks in pg_start_backup()
+ and pg_stop_backup() (Andres Freund, Magnus Hagander)
+
+
+
+ The previous coding might attempt to do catalog access when it
+ shouldn't.
+
+
+
+
+
+ Accept SHIFT_JIS as an encoding name for locale checking
+ purposes (Tatsuo Ishii)
+
+
+
+
+
+ Fix *-qualification of named parameters in SQL-language
+ functions (Tom Lane)
+
+
+
+ Given a composite-type parameter
+ named foo, $1.* worked fine,
+ but foo.* not so much.
+
+
+
+
+
+ Fix misbehavior of PQhost() on Windows (Fujii Masao)
+
+
+
+ It should return localhost if no host has been specified.
+
+
+
+
+
+ Improve error handling in libpq and psql
+ for failures during COPY TO STDOUT/FROM STDIN (Tom Lane)
+
+
+
+ In particular this fixes an infinite loop that could occur in 9.2 and
+ up if the server connection was lost during COPY FROM
+ STDIN. Variants of that scenario might be possible in older
+ versions, or with other client applications.
+
+
+
+
+
+ Fix incorrect translation handling in
+ some psql \d commands
+ (Peter Eisentraut, Tom Lane)
+
+
+
+
+
+
+
+
+ Ensure pg_basebackup's background process is killed
+ when exiting its foreground process (Magnus Hagander)
+
+
+
+
+
+ Fix possible incorrect printing of filenames
+ in pg_basebackup's verbose mode (Magnus Hagander)
+
+
+
+
+
+ Avoid including tablespaces inside PGDATA twice in base backups
+ (Dimitri Fontaine, Magnus Hagander)
+
+
+
+
+
+ Fix misaligned descriptors in ecpg (MauMau)
+
+
+
+
+
+ In ecpg, handle lack of a hostname in the connection
+ parameters properly (Michael Meskes)
+
+
+
+
+
+ Fix performance regression in contrib/dblink connection
+ startup (Joe Conway)
+
+
+
+ Avoid an unnecessary round trip when client and server encodings match.
+
+
+
+
+
+ In contrib/isn, fix incorrect calculation of the check
+ digit for ISMN values (Fabien Coelho)
+
+
+
+
+
+ Fix contrib/pg_stat_statement's handling
+ of CURRENT_DATE and related constructs (Kyotaro
+ Horiguchi)
+
+
+
+
+
+ Ensure client-code-only installation procedure works as documented
+ (Peter Eisentraut)
+
+
+
+
+
+ In Mingw and Cygwin builds, install the libpq DLL
+ in the bin directory (Andrew Dunstan)
+
+
+
+ This duplicates what the MSVC build has long done. It should fix
+ problems with programs like psql failing to start
+ because they can't find the DLL.
+
+
+
+
+
+ Avoid using the deprecated dllwrap tool in Cygwin builds
+ (Marco Atzeri)
+
+
+
+
+
+ Don't generate plain-text HISTORY
+ and src/test/regress/README files anymore (Tom Lane)
+
+
+
+ These text files duplicated the main HTML and PDF documentation
+ formats. The trouble involved in maintaining them greatly outweighs
+ the likely audience for plain-text format. Distribution tarballs
+ will still contain files by these names, but they'll just be stubs
+ directing the reader to consult the main documentation.
+ The plain-text INSTALL file will still be maintained, as
+ there is arguably a use-case for that.
+
+
+
+
+
+ Update time zone data files to tzdata release 2013i
+ for DST law changes in Jordan and historical changes in Cuba.
+
+
+
+ In addition, the zones Asia/Riyadh87,
+ Asia/Riyadh88, and Asia/Riyadh89 have been
+ removed, as they are no longer maintained by IANA, and never
+ represented actual civil timekeeping practice.
