As a release +candidate, PostgreSQL 13 RC 1 will be mostly identical to the initial release of +PostgreSQL 13, though some more fixes may be applied prior to the general +availability of PostgreSQL 13. + +The planned date for the general availability of PostgreSQL 13 is September 24, +2020. Please see the "Release Schedule" section for more details. + +Upgrading to PostgreSQL 13 RC 1 +------------------------------- + +To upgrade to PostgreSQL 13 RC 1 from Beta 3 or an earlier version of +PostgreSQL 13, you will need to use a strategy similar to upgrading between +major versions of PostgreSQL (e.g. `pg_upgrade` or `pg_dump` / `pg_restore`). +For more information, please visit the documentation section on +[upgrading](https://www.postgresql.org/docs/13/static/upgrading.html). + +Changes Since 13 Beta 3 +----------------------- + +There have been many bug fixes for PostgreSQL 13 reported during the Beta 3 +period and applied to this release candidate. These include: + +* Adjustments to the costing model for hash aggregates that spill to disk. +* Adjustments to the output of `EXPLAIN (BUFFERS)`. +* Display the stats target of extended statistics in the output of `\d`. + +For a detailed list of fixes, please visit the +[open items](https://wiki.postgresql.org/wiki/PostgreSQL_13_Open_Items#resolved_before_13rc1) +page. + +Release Schedule +---------------- + +This is the first release candidate for PostgreSQL 13. Unless an issue is +discovered that warrants a delay or to produce an additional release candidate, +PostgreSQL 13 should be made generally available on September 24, 2020. + +For further information please see the +[Beta Testing](https://www.postgresql.org/developer/beta/) page. + +Links +----- + +* [Download](https://www.postgresql.org/download/) +* [Beta Testing Information](https://www.postgresql.org/developer/beta/) +* [PostgreSQL 13 RC 1 Release Notes](https://www.postgresql.org/docs/13/static/release-13.html) +* [PostgreSQL 13 Open Issues](https://wiki.postgresql.org/wiki/PostgreSQL_13_Open_Items) +* [Submit a Bug](https://www.postgresql.org/account/submitbug/) +* [Follow @postgresql on Twitter](https://www.twitter.com/postgresql) -- 2.39.5
