[GENERAL] contrecord is requested

2017-09-11 Thread Scott Marlowe
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 2E7/4028" And fails to get back up. Is this a known issue? Possible bug in the continuation record co
