We are seeing situation like this: 1. 9.2.4 database 2. Master settings: name | setting ---------------------------+--------------- fsync | on synchronize_seqscans | on synchronous_commit | remote_write synchronous_standby_names | * wal_sync_method | open_datasync (5 rows) Yet, every now and then we're getting: FATAL: requested WAL segment * has already been removed Assuming no part of the system is issuing "set synchronous_commit = off", how can we get in such situation?
