Hi, There is a description about streaming replication in the doc: ---------------------------------------------------------- 25.2.5. Streaming Replication
: : If you set up a WAL archive that's accessible from the standby, wal_keep_segments is not required as the standby can always use the archive to catch up. ---------------------------------------------------------- I think this description is somewhat inadequate. Since recovery using WAL archive is file based, it may cause long replication delay. I think even if WAL archive is set up, we should set wal_keep_segments to proper value, not 0. Recovery from WAL archive should be the last resort, shouldn't be? -- Tatsuo Ishii SRA OSS, Inc.
