Update postgres RPM GPG key

[p-j-smith]

Fixes #16

• the GPG key for the latest version of the postgres RPM has moved to a new location - update postgresql_rpm_gpg_key_pgdg to reflect this

Do we know if this is a permanent fix? Or is there a chance this will happen again? We should also decide on a release policy, I would quite like this change - but happy to work on main for now.

I'm not sure how permanent this fix is, but it sounds like this issue crops up often

Yeah we should. I think given deployment is currently broken for rocky 9 we should make a release once this is merged
