If yes, how to go about it. I am quite new to Postgres. Any help/ > suggestions will be greatly appreciated. Yeah, the master doesn't have/contains the requested WAL-File, you have to rebuild the replication with a fresh copy from the master. You can use pg_basebackup, it's well documented. For the future: increase wal_keep_segments and/or use physical replications slots, if you are using 9.4 or higher. Andreas -- Really, I'm not out to destroy Microsoft.
