Subject: Guidance Required for PostgreSQL Major Version Upgrade in Pacemaker HA Cluster
Date: Fri, 17 Apr 2026 11:25:11 +0530
Message-ID: <CAEgpDvG76VG4YVq8SayUb+tV2NsB+BfHxE=zBSu+9bxXiChi7Q@mail.gmail.com> (raw)

Dear PostgreSQL Community,

I am currently planning a major upgrade of our PostgreSQL environment to
the latest stable version and would appreciate your guidance on the best
approach.

Our current setup consists of a high-availability cluster managed by
Pacemaker on a Linux operating system, configured in a master–slave
(primary–standby) architecture. Given the critical nature of this
environment, we want to ensure the upgrade is performed with minimal
downtime and without compromising data integrity or cluster stability.

I would be grateful if the community could share insights or best practices
on the following:

   -

   Recommended upgrade strategy (in-place upgrade vs. logical replication
   vs. dump/restore) for a Pacemaker-managed HA cluster
   -

   Handling failover and cluster resources during the upgrade process
   -

   Any precautions or common pitfalls specific to Pacemaker-based
   PostgreSQL clusters
   -

   Suggested sequence of steps to ensure a smooth and safe transition

*Details :*
Current version of PostgreSQL is *14.6 *
OS: Linux
HA :Pacemaker Based
Master -Slave  --Setup

If anyone has experience performing a similar upgrade or can point me to
relevant documentation or case studies, that would be extremely helpful.

Thank you in advance for your support.
