I understand your point and appreciate the clarification.
I have reviewed the references and now have a better understanding of the minor upgrade process.
However, my concern lies in the fact that we are working with production servers, where downtime is not acceptable.
Additionally, if a failover occurs due to a network issue or any other disaster, setting up replication again requires running the
pg_basebackupcommand. For large databases, this process becomes a significant challenge, as runningpg_basebackupfor the entire cluster can be time-consuming and resource-intensive.
A comment and a question:
1) pg_basebackup runs just fine from cron. Thus, "time-consuming" (which you described as 2-3 hours) isn't that critical.
2) What do you mean by resource-intensive? If it means network bandwidth, then read the pg_basebackup man page.
