RedHat 9 - wrong version number

[kris9854]

Hi @geerlingguy
The __postgresql_version: "10"
might be wrong as the main postgresql package is version 13.
The main package is provided in the appstream.

Unless im wrong then just ignore me :)

Agreed. As per RHEL documentation the initial version should be v13.

Added #257 to address this
