databases/postgresql18: Upgrade to RC 1
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.
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:
