My apologies for taking a couple of weeks before coming back to this
thread. I have been informed a couple of days ago about a report
which is showing the same symptoms as what you have reported. Please
note that we have two other threads which refer to the same problem as
what you have here:
https://www.postgresql.org/message-id/15567-a9ff747c5e7c031c%40postgresql.org
https://www.postgresql.org/message-id/CAJ%2BDhQaf9ZMkqPPnapu06mvMFe-b_K4NGF%2B-MV%2Be%3DJB2edF4cQ%40mail.gmail.com
All of them refer to an infinite loop reachable in the startup process
when we read an incorrect incomplete record just after a failover or
when a WAL receiver restarts. Not sure which way is best in order to
fix all of them in one shot, I am still considering what the possible
options at hand are here.
