6. POSTGRESQL server update from V16 to V18
Never ever make more than 1 version jump with postgresql servers. the
imgrationtool does not handle it at all:
F43vm # postgresql-upgrade --upgrade-ids
postgresql - Upgrade data from system PostgreSQL version (PostgreSQL 17)
No support for 16 => you have to revert the database, export databases,
upgrade server and reimport it.
Actually postgres is fine with it, it's just the way that the
packaging in Fedora works that stops you doing it because the
postgresql-upgrade package is always one version behind.
You don't have to dump and reload though - you can uninstall
the postgresql packages and install the postgresql17 ones and
upgrade, then uninstall those and install the postgresql ones
again and do a second upgrade.
Now that Fedora is packaging multiple versions there isn't
really any need for the -upgrade packages, but it would require
the versions packages to be parallel installable which they
aren't at the moment.
