Message-ID: <[email protected]> (raw)
The PostgreSQL Global Development Group announces that the first release
candidate of PostgreSQL 18 is now available for download. As a release
candidate, PostgreSQL 18 RC 1 will be mostly identical to the initial release of
PostgreSQL 18, though some more fixes may be applied prior to the general
availability of PostgreSQL 18.
The planned date for the general availability of PostgreSQL 18 is
September 25, 2025. Please see the "Release Schedule" section for more details.
Upgrading to PostgreSQL 18 RC 1
-------------------------------
To upgrade to PostgreSQL 18 RC 1 from earlier versions of PostgreSQL, you will
need to use a major version upgrade strategy, e.g. `pg_upgrade` or
`pg_dump` / `pg_restore`. For more information, please visit the documentation
section on [upgrading](https://www.postgresql.org/docs/18/upgrading.html):
[https://www.postgresql.org/docs/18/upgrading.html](https://www.postgresql.org/docs/18/upgrading.html)
Changes Since 18 Beta 3
-----------------------
Several bug fixes were applied for PostgreSQL 18 during the Beta 3 period. These
include:
* Skip vacuuming virtual generated columns when using `vacuumdb --missing-stats-only`.
* Added recommendation on when to reindex full-text search and `pg_trgm` indexes after using `pg_upgrade`.
For a detailed list of fixes, please visit the
[open items](https://wiki.postgresql.org/wiki/PostgreSQL_18_Open_Items#resolved_before_18rc1)
page.
Release Schedule
----------------
This is the first release candidate for PostgreSQL 18. Unless an issue is
discovered that warrants a delay or to produce an additional release candidate,
PostgreSQL 18 should be made generally available on September 25, 2025.
