DETAIL: pg_rewind: servers diverged at WAL location 0/9000000 on timeline 1

Hello,

Currently we are working on setting up replication and testing failover scenarios and failback. During our testing, failover is getting successful. During Failback, when we are reverting the original primary instance as the new standby, we are getting pg_rewind errors. Kindly can someone check and let us know.
