So I read that on RHEL 7 you get PostgreSQL to max Version 9.2 but I found on this page that you can add a repository to get a newer version installed as well, but don’t know if it works or if I need to upgrade to RHEL 8 first.


Steps to reproduce the behavior:

  • yum upgrade

CentOS 7 or 8 it doesn’t matter.
You need a fitting postgresql version which can be installed via either additional repositories or manual installation methods (don’t).

There are tons of migration path howtos - pgsql even comes with a tool for that:

You should have a backup of course.
If that’s too difficult for you, which is absolutely okay, you could also go with a system migration by backing up and restoring: Backup and Restore — Zammad documentation
