In READ COMMITTED mode, an update that finds that its target row was just updated by a concurrent transaction will recheck the query's WHERE conditions on the updated row. Fix inconsistent rechecking of concurrently-updated rows during MERGE

Some cases involving an IS NULL condition on one of the partition keys could result in a crash. Fix partition step generation and runtime partition pruning for hash-partitioned tables with multiple partition keys This bug might have caused unexpected failures while trying to insert large interval values into such an index. Avoid calculation overflows in BRIN interval_minmax_multi_ops indexes with extreme interval values Infinities were mistakenly treated as having distance zero rather than a large distance from other values, causing poor decisions about which entries to merge. Process large timestamp and timestamptz values more sanely in BRIN datetime_minmax_multi_ops indexes Reindexing BRIN minmax_multi indexes on date columns is advisable. The index still produces correct results, but is much less efficient than it should be. The distance calculation for dates was backward, causing poor decisions about which entries to merge. Process date values more sanely in BRIN datetime_minmax_multi_ops indexes Users should reindex any btree indexes on interval columns. Moreover, after updating amcheck will report an error for almost all such indexes. This oversight can cause incorrect results from index-only scans. This breaks assumptions made by btree de-duplication, so interval columns need to be excluded from de-duplication. There are interval values that are distinguishable but compare equal, for example 24:00:00 and 1 day. Prevent de-duplication of btree index entries for interval columns It may be advisable to reindex all GiST indexes after installing this update. This error could result in incorrect answers from subsequent index searches. Fix a case where the location of a page downlink was incorrectly tracked, and introduce some logic to allow recovering from such situations rather than silently doing the wrong thing. Fix misbehavior during recursive page split in GiST index build The PostgreSQL Project thanks Hemanth Sandrana and Mahendrakar Srinivasarao for reporting this problem No specific security consequences are known for that oversight, but it might be significant for some extensions. Also ensure that the is_superuser parameter is set correctly in such processes. The security implications of cancelling one of these process types are fairly small so far as the core code goes Treat that as indicating superuser ownership. It was able to signal these background processes, though, because they advertise a role OID of zero.

The documentation says that pg_signal_backend cannot issue signals to superuser-owned processes. Prevent the pg_signal_backend role from signalling background workers and autovacuum processes The PostgreSQL Project thanks Pedro Gallegos for reporting this problem Memory stomps that are potentially exploitable for arbitrary code execution are possible, and so is disclosure of server memory. When assigning new elements to array subscripts that are outside the current array bounds, an undetected integer overflow could occur in edge cases. Detect integer overflow while computing new array dimensions The PostgreSQL Project thanks Jingzhou Fu for reporting this problem This error led to a text-type value being interpreted as an unknown-type value Fix handling of unknown-type arguments in DISTINCT 'any' aggregate functions See the fourth through seventh changelog entries below. It is advisable to REINDEX potentially-affected indexes after installing this update. However, several mistakes have been discovered that could lead to certain types of indexes yielding wrong search results or being unnecessarily inefficient. Net, Perl, Python, Ruby, Tcl, ODBC, among others, and exceptional documentation (table sizes can go up to 32 TB).Īlso Available: Download PostgreSQL for Windows It has native programming interfaces for C/C++, Java. It also supports storage of binary large objects, including pictures, sounds, or video. It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP.

It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). PostgreSQL for macOS is the default database on Mac OS X Server as of version 10.7. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness. PostgreSQL for Mac is a powerful, open source object-relational database system.
