Please let us know what is the proper way to use pg_rewind. How can I know when pg_rewind should not be used (after master crash?) can pgpool assist with that?
I have not tried it but yes, pg_rewind cannot be used after
crash. There's nothing so far Pgpool-II can help in this regard. Once
I thought about teaching Pgpool-II if it's after crash or scheduled
failover. I don't have time to implement it for now though.
