What did pg_rewind tell you after the first run? If you remove the set of WAL segments on the rewound instance and let it replay only segments from the archive, are you able to get past? There is an inconsistency in the WAL records you are trying to replay. In this case a contrecord refers to a WAL record split across multiple pages. The WAL reader is expecting one, and cannot find it. And that's not normal. My bet is that something is wrong in your failover flow which you think is right. It is hard to get that right. -- Michael
