So we have a db we're trying to rewind and get synced to the master.
pg_rewind says it doesn't need rewinding, and when we try to bring it
up, it gets this error:
"contrecord is requested by 2E7/40000028"
And fails to get back up.
Is this a known issue? Possible bug in the continuation record code?
The only references I can find for it are in the xlogreader code.
I've seen this twice lately and both times it was user error.
One time someone who shall remain nameless made a replica of a remote QA server using "pg_basebackup -R ...", but then copied the *.conf files **including recovery.conf** from the running replica of the the remote production server into the new directory for the replica of the remote QA server. So primary_conninfo had been overwritten to point to the wrong master server.
The other time someone who shall also remain nameless accidentally fully opened up a newly cloned (from a cold backup, I think) of an dummy benchmarking server, instead of putting it into standby. And then tried to shut it down and re-open it as a standby without doing a full refresh. But of course it was too late to do that.
