The PostgreSQL Global Development Group announces today that the third
beta release of PostgreSQL 9.6 is available for download. This release
contains previews of all of the features which will be available in
the final release of version 9.6, including fixes to many of the
issues found in the first and second betas. Users are encouraged to
continue testing their applications against 9.6 beta 3.
Changes Since Beta 2
--------------------
Our users and contributors tested the first two betas, and found and
reported many bugs and usability issues. This beta release fixes many
of those issues. If you reported an issue, please test this beta to
ensure that it's completely fixed.
This included many more fixes to parallel query:
* adding support for TABLESAMPLE
* correcting cost data in Gather nodes
* check parallel-safety of all appended relations
* fix planner issues with initPlans
* fix several issues with client_encoding
* clean up EXPLAIN output for parallel queries
* multiple changes to parallel aggregation internals
Among the other issues addressed were:
* add conninfo field to pg_stat_wal_receiver
* clear all-frozen visibilitymap status
when locking tuples
* correctly dump database and tablespace ACLs
* avoid invalidating all foreign-join cached plans
when user mappings change
* fix nested NOT operation cleanup in tsquery
* allow IMPORT FOREIGN SCHEMA within pl/pgsql
* print a given subplan only once in EXPLAIN
* change the GetForeignUpperPaths API
* fix several issues in postgres_fdw
* added many additional regression tests
* many documentation updates and clarifications
* multiple translation updates for the docs
Due to changes in system catalogs, a pg_upgrade or dump and restore
will be required for users migrating databases from earlier betas.
This includes a version update to the pg_control tool, making it
incompatible with PostgreSQL 9.4 and earlier. This beta also includes
patches to many issues shared with earlier versions, which will be
updated in an upcoming minor release.
Note that some known issues remain unfixed. Before reporting a bug in
the beta, please check the Open Items page.
Beta Schedule
-------------
This is the third beta release of version 9.6. The PostgreSQL Project
will release additional betas as required for testing, followed by one
or more release candidates, until the final release in late 2016. For
further information please see the Beta Testing page.
