I am running pg14.4. I use WAL replication in a stand-by server which is 7-days behind primary (recovery_min_apply_delay = 7d)
My replication is stuck. It looks like it is repeatedly applying same WAL file. The next WAL file(s) are very much there.
I restarted cluster but it didn’t fix the issue.
I appreciate any help you can provide before I rebuild the stand-by. I am trying to find the root cause. If 0000000100013D94000000FF is corrupted how can we tell?
