Hi All,

We are planning to upgrade the operating system from Centos 7 on Primary 
and Standby PostgreSQL nodes that use streaming replication to RHEL 8.
What is the recommended order to upgrade OS from Centos 7 to RHEL 8? 
Standby first, then Primary? Can there be a small time gap between the 
upgrades or not?

Thanks,
Rahat
