+
+ Release 8.4.22
+
+
+ Release Date
+ 2014-07-24
+
+
+
+ This release contains a variety of fixes from 8.4.21.
+ For information about new features in the 8.4 major release, see
+ .
+
+
+
+ This is expected to be the last PostgreSQL release
+ in the 8.4.X series. Users are encouraged to update to a newer
+ release branch soon.
+
+
+
+ Migration to Version 8.4.22
+
+
+ A dump/restore is not required for those running 8.4.X.
+
+
+
+ However, this release corrects an index corruption problem in some GiST
+ indexes. See the first changelog entry below to find out whether your
+ installation has been affected and what steps you should take if so.
+
+
+
+ Also, if you are upgrading from a version earlier than 8.4.19,
+ see .
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Correctly initialize padding bytes in contrib/btree_gist
+ indexes on bit columns (Heikki Linnakangas)
+
+
+
+ This error could result in incorrect query results due to values that
+ should compare equal not being seen as equal.
+ Users with GiST indexes on bit or bit varying
+ columns should REINDEX those indexes after installing this
+ update.
+
+
+
+
+
+ Protect against torn pages when deleting GIN list pages (Heikki
+ Linnakangas)
+
+
+
+ This fix prevents possible index corruption if a system crash occurs
+ while the page update is being written to disk.
+
+
+
+
+
+ Fix possibly-incorrect cache invalidation during nested calls
+ to ReceiveSharedInvalidMessages (Andres Freund)
+
+
+
+
+
+ Don't assume a subquery's output is unique if there's a set-returning
+ function in its targetlist (David Rowley)
+
+
+
+ This oversight could lead to misoptimization of constructs
+ like WHERE x IN (SELECT y, generate_series(1,10) FROM t GROUP
+ BY y).
+
+
+
+
+
+ Fix failure to detoast fields in composite elements of structured
+ types (Tom Lane)
+
+
+
+ This corrects cases where TOAST pointers could be copied into other
+ tables without being dereferenced. If the original data is later
+ deleted, it would lead to errors like missing chunk number 0
+ for toast value ... when the now-dangling pointer is used.
+
+
+
+
+
+ Fix record type has not been registered failures with
+ whole-row references to the output of Append plan nodes (Tom Lane)
+
+
+
+
+
+ Fix possible crash when invoking a user-defined function while
+ rewinding a cursor (Tom Lane)
+
+
+
+
+
+ Fix query-lifespan memory leak while evaluating the arguments for a
+ function in FROM (Tom Lane)
+
+
+
+
+
+ Fix session-lifespan memory leaks in regular-expression processing
+ (Tom Lane, Arthur O'Dwyer, Greg Stark)
+
+
+
+
+
+ Fix data encoding error in hungarian.stop (Tom Lane)
+
+
+
+
+
+ Fix liveness checks for rows that were inserted in the current
+ transaction and then deleted by a now-rolled-back subtransaction
+ (Andres Freund)
+
+
+
+ This could cause problems (at least spurious warnings, and at worst an
+ infinite loop) if CREATE INDEX or CLUSTER were
+ done later in the same transaction.
+
+
+
+
+
+ Clear pg_stat_activity.xact_start
+ during PREPARE TRANSACTION (Andres Freund)
+
+
+
+ After the PREPARE, the originating session is no longer in
+ a transaction, so it should not continue to display a transaction
+ start time.
+
+
+
+
+
+ Fix REASSIGN OWNED to not fail for text search objects
+ (Álvaro Herrera)
+
+
+
+
+
+ Block signals during postmaster startup (Tom Lane)
+
+
+
+ This ensures that the postmaster will properly clean up after itself
+ if, for example, it receives SIGINT while still
+ starting up.
+
+
+
+
+
+ Secure Unix-domain sockets of temporary postmasters started during
+ make check (Noah Misch)
+
+
+
+ Any local user able to access the socket file could connect as the
+ server's bootstrap superuser, then proceed to execute arbitrary code as
+ the operating-system user running the test, as we previously noted in
+ CVE-2014-0067. This change defends against that risk by placing the
+ server's socket in a temporary, mode 0700 subdirectory
+ of /tmp. The hazard remains however on platforms where
+ Unix sockets are not supported, notably Windows, because then the
+ temporary postmaster must accept local TCP connections.
+
+
+
+ A useful side effect of this change is to simplify
+ make check testing in builds that
+ override DEFAULT_PGSOCKET_DIR. Popular non-default values
+ like /var/run/postgresql are often not writable by the
+ build user, requiring workarounds that will no longer be necessary.
+
+
+
+
+
+ On Windows, allow new sessions to absorb values of PGC_BACKEND
+ parameters (such as ) from the
+ configuration file (Amit Kapila)
+
+
+
+ Previously, if such a parameter were changed in the file post-startup,
+ the change would have no effect.
+
+
+
+
+
+ Properly quote executable path names on Windows (Nikhil Deshpande)
+
+
+
+ This oversight could cause initdb
+ and pg_upgrade to fail on Windows, if the installation
+ path contained both spaces and @ signs.
+
+
+
+
+
+ Fix linking of libpython on OS X (Tom Lane)
+
+
+
+ The method we previously used can fail with the Python library
+ supplied by Xcode 5.0 and later.
+
+
+
+
+
+ Avoid buffer bloat in libpq when the server
+ consistently sends data faster than the client can absorb it
+ (Shin-ichi Morita, Tom Lane)
+
+
+
+ libpq could be coerced into enlarging its input buffer
+ until it runs out of memory (which would be reported misleadingly
+ as lost synchronization with server). Under ordinary
+ circumstances it's quite far-fetched that data could be continuously
+ transmitted more quickly than the recv() loop can
+ absorb it, but this has been observed when the client is artificially
+ slowed by scheduler constraints.
+
+
+
+
+
+ Ensure that LDAP lookup attempts in libpq time out as
+ intended (Laurenz Albe)
+
+
+
+
+
+ Fix pg_restore's processing of old-style large object
+ comments (Tom Lane)
+
+
+
+ A direct-to-database restore from an archive file generated by a
+ pre-9.0 version of pg_dump would usually fail if the
+ archive contained more than a few comments for large objects.
+
+
+
+
+
+ In contrib/pgcrypto functions, ensure sensitive
+ information is cleared from stack variables before returning
+ (Marko Kreen)
+
+
+
+
+
+ In contrib/uuid-ossp, cache the state of the OSSP UUID
+ library across calls (Tom Lane)
+
+
+
+ This improves the efficiency of UUID generation and reduces the amount
+ of entropy drawn from /dev/urandom, on platforms that
+ have that.
+
+
+
+
+
+ Update time zone data files to tzdata release 2014e
+ for DST law changes in Crimea, Egypt, and Morocco.

+ A dump/restore is not required for those running 9.2.X.
+
+
+
+ However, this release corrects an index corruption problem in some GiST
+ indexes. See the first changelog entry below to find out whether your
+ installation has been affected and what steps you should take if so.
+
+
+
+ Also, if you are upgrading from a version earlier than 9.2.6,

+
+
+ Changes
+
+
+
+
+
+ Correctly initialize padding bytes in contrib/btree_gist
+ indexes on bit columns (Heikki Linnakangas)
+
+
+
+ This error could result in incorrect query results due to values that
+ should compare equal not being seen as equal.
+ Users with GiST indexes on bit or bit varying
+ columns should REINDEX those indexes after installing this
+ update.
+
+
+
+
+
+ Protect against torn pages when deleting GIN list pages (Heikki
+ Linnakangas)
+
+
+
+ This fix prevents possible index corruption if a system crash occurs
+ while the page update is being written to disk.
+
+
+
+
+
+ Don't clear the right-link of a GiST index page while replaying
+ updates from WAL (Heikki Linnakangas)
+
+
+
+ This error could lead to transiently wrong answers from GiST index
+ scans performed in Hot Standby.
+
+
+
+
+
+ Fix corner-case infinite loop during insertion into an SP-GiST text
+ index (Tom Lane)
+
+
+
+
+
+ Fix feedback status when is
+ turned off on-the-fly (Simon Riggs)
+
+
+
+
+
+ Fix possibly-incorrect cache invalidation during nested calls
+ to ReceiveSharedInvalidMessages (Andres Freund)
+
+
+
+
+
+ Fix planner's mishandling of nested PlaceHolderVars generated in
+ nested-nestloop plans (Tom Lane)
+
+
+
+ This oversight could result in variable not found in subplan
+ target lists errors, or in silently wrong query results.
+
+
+
+
+
+ Fix could not find pathkey item to sort planner failures
+ with UNION ALL over subqueries reading from tables with
+ inheritance children (Tom Lane)
+
+
+
+
+
+ Don't assume a subquery's output is unique if there's a set-returning
+ function in its targetlist (David Rowley)
+
+
+
+ This oversight could lead to misoptimization of constructs
+ like WHERE x IN (SELECT y, generate_series(1,10) FROM t GROUP
+ BY y).
+
+
+
+
+
+ Improve planner to drop constant-NULL inputs
+ of AND/OR when possible (Tom Lane)
+
+
+
+ This change fixes some cases where the more aggressive parameter
+ substitution done by 9.2 and later can lead to a worse plan than
+ older versions produced.
+
+
+
+
+
+ Fix identification of input type category in to_json()
+ and friends (Tom Lane)
+
+
+
+ This is known to have led to inadequate quoting of money
+ fields in the JSON result, and there may have been wrong
+ results for other data types as well.
+
+
+
+
+
+ Fix failure to detoast fields in composite elements of structured
+ types (Tom Lane)
+
+
+
+ This corrects cases where TOAST pointers could be copied into other
+ tables without being dereferenced. If the original data is later
+ deleted, it would lead to errors like missing chunk number 0
+ for toast value ... when the now-dangling pointer is used.
+
+
+
+
+
+ Fix record type has not been registered failures with
+ whole-row references to the output of Append plan nodes (Tom Lane)
+
+
+
+
+
+ Fix possible crash when invoking a user-defined function while
+ rewinding a cursor (Tom Lane)
+
+
+
+
+
+ Fix query-lifespan memory leak while evaluating the arguments for a
+ function in FROM (Tom Lane)
+
+
+
+
+
+ Fix session-lifespan memory leaks in regular-expression processing
+ (Tom Lane, Arthur O'Dwyer, Greg Stark)
+
+
+
+
+
+ Fix data encoding error in hungarian.stop (Tom Lane)
+
+
+
+
+
+ Prevent foreign tables from being created with OIDS
+ when is true
+ (Etsuro Fujita)
+
+
+
+
+
+ Fix liveness checks for rows that were inserted in the current
+ transaction and then deleted by a now-rolled-back subtransaction
+ (Andres Freund)
+
+
+
+ This could cause problems (at least spurious warnings, and at worst an
+ infinite loop) if CREATE INDEX or CLUSTER were
+ done later in the same transaction.
+
+
+
+
+
+ Clear pg_stat_activity.xact_start
+ during PREPARE TRANSACTION (Andres Freund)
+
+
+
+ After the PREPARE, the originating session is no longer in
+ a transaction, so it should not continue to display a transaction
+ start time.
+
+
+
+
+
+ Fix REASSIGN OWNED to not fail for text search objects
+ (Álvaro Herrera)
+
+
+
+
+
+ Block signals during postmaster startup (Tom Lane)
+
+
+
+ This ensures that the postmaster will properly clean up after itself
+ if, for example, it receives SIGINT while still
+ starting up.
+
+
+
+
+
+ Fix client host name lookup when processing pg_hba.conf
+ entries that specify host names instead of IP addresses (Tom Lane)
+
+
+
+ Ensure that reverse-DNS lookup failures are reported, instead of just
+ silently not matching such entries. Also ensure that we make only
+ one reverse-DNS lookup attempt per connection, not one per host name
+ entry, which is what previously happened if the lookup attempts failed.
+
+
+
+
+
+ Allow the root user to use postgres -C variable and
+ postgres --describe-config (MauMau)
+
+
+
+ The prohibition on starting the server as root does not need to extend
+ to these operations, and relaxing it prevents failure
+ of pg_ctl in some scenarios.
+
+
+
+
+
+ Secure Unix-domain sockets of temporary postmasters started during
+ make check (Noah Misch)
+
+
+
+ Any local user able to access the socket file could connect as the
+ server's bootstrap superuser, then proceed to execute arbitrary code as
+ the operating-system user running the test, as we previously noted in
+ CVE-2014-0067. This change defends against that risk by placing the
+ server's socket in a temporary, mode 0700 subdirectory
+ of /tmp. The hazard remains however on platforms where
+ Unix sockets are not supported, notably Windows, because then the
+ temporary postmaster must accept local TCP connections.
+
+
+
+ A useful side effect of this change is to simplify
+ make check testing in builds that
+ override DEFAULT_PGSOCKET_DIR. Popular non-default values
+ like /var/run/postgresql are often not writable by the
+ build user, requiring workarounds that will no longer be necessary.
+
+
+
+
+
+ Fix tablespace creation WAL replay to work on Windows (MauMau)
+
+
+
+
+
+ Fix detection of socket creation failures on Windows (Bruce Momjian)
+
+
+
+
+
+ On Windows, allow new sessions to absorb values of PGC_BACKEND
+ parameters (such as ) from the
+ configuration file (Amit Kapila)
+
+
+
+ Previously, if such a parameter were changed in the file post-startup,
+ the change would have no effect.
+
+
+
+
+
+ Properly quote executable path names on Windows (Nikhil Deshpande)
+
+
+
+ This oversight could cause initdb
+ and pg_upgrade to fail on Windows, if the installation
+ path contained both spaces and @ signs.
+
+
+
+
+
+ Fix linking of libpython on OS X (Tom Lane)
+
+
+
+ The method we previously used can fail with the Python library
+ supplied by Xcode 5.0 and later.
+
+
+
+
+
+ Avoid buffer bloat in libpq when the server
+ consistently sends data faster than the client can absorb it
+ (Shin-ichi Morita, Tom Lane)
+
+
+
+ libpq could be coerced into enlarging its input buffer
+ until it runs out of memory (which would be reported misleadingly
+ as lost synchronization with server). Under ordinary
+ circumstances it's quite far-fetched that data could be continuously
+ transmitted more quickly than the recv() loop can
+ absorb it, but this has been observed when the client is artificially
+ slowed by scheduler constraints.
+
+
+
+
+
+ Ensure that LDAP lookup attempts in libpq time out as
+ intended (Laurenz Albe)
+
+
+
+
+
+ Fix ecpg to do the right thing when an array
+ of char * is the target for a FETCH statement returning more
+ than one row, as well as some other array-handling fixes
+ (Ashutosh Bapat)
+
+
+
+
+
+ Fix pg_restore's processing of old-style large object
+ comments (Tom Lane)
+
+
+
+ A direct-to-database restore from an archive file generated by a
+ pre-9.0 version of pg_dump would usually fail if the
+ archive contained more than a few comments for large objects.
+
+
+
+
+
+ Fix pg_upgrade for cases where the new server creates
+ a TOAST table but the old version did not (Bruce Momjian)
+
+
+
+ This rare situation would manifest as relation OID mismatch
+ errors.
+
+
+
+
+
+ Prevent contrib/auto_explain from changing the output of
+ a user's EXPLAIN (Tom Lane)
+
+
+
+ If auto_explain is active, it could cause
+ an EXPLAIN (ANALYZE, TIMING OFF) command to nonetheless
+ print timing information.
+
+
+
+
+
+ Fix query-lifespan memory leak in contrib/dblink
+ (MauMau, Joe Conway)
+
+
+
+
+
+ In contrib/pgcrypto functions, ensure sensitive
+ information is cleared from stack variables before returning
+ (Marko Kreen)
+
+
+
+
+
+ Prevent use of already-freed memory in
+ contrib/pgstattuple's pgstat_heap()
+ (Noah Misch)
+
+
+
+
+
+ In contrib/uuid-ossp, cache the state of the OSSP UUID
+ library across calls (Tom Lane)
+
+
+
+ This improves the efficiency of UUID generation and reduces the amount
+ of entropy drawn from /dev/urandom, on platforms that
+ have that.
+
+
+
+
+
+ Update time zone data files to tzdata release 2014e
+ for DST law changes in Crimea, Egypt, and Morocco.
