Re: Heads up: Barman, Patroni, psycopg and Python 3.12

Hi,

This is now completed except RHEL 9 - aarch64 (fat fingers on that
platform, so will work on that tomorrow).

https://github.com/pgdg-packaging/pgdg-rpms/issues/16

I had to introduce new packages for RHEL 8 and 9. Please note that I had
to use Python 3.11 on SLES 15 to use more packages in their repo.

Currently we use Python 3.13 on Fedora, Python 3.12 on RHEL 10, 9 and 8
and Python 3.11 on SLES 15.

I'd like to thank Seda Yavuz for testing Patroni packages extensively.

Still if you see any issues, please report it to us:

Regards, Devrim
