Thanks for your response, 

I would like to get the exact commands to use.

apt-cache showpkg postgresql-15
apt install <package-name>=<version> 

Note: Before downgrade operation please make sure you take the proper backup.

Hi,
I think the only solution is to:

Backup Your Data
Stop PostgreSQL
Uninstall PostgreSQL 15.8
Install PostgreSQL 15.7
Check Replication

Hi Team,

We have observed post OS patching one of our replica server got auto upgraded from 15.7 to 15.8 in Ubuntu , we wanted to downgrade the postgres version to match with our primary node.

( replic sync also not happening due this version mis match )

Pls advise.

Thanks in advance.
