We can know the LSN of last committed WAL record on primary by using pg_current_xlog_location(). It seems there's no API to know the time when the WAL record was created. I would like to know standby delay by using pg_last_xact_replay_timestamp() and such that API.
If there's no such a API, it would be useful to invent usch an API IMO. Best regards, -- Tatsuo Ishii SRA OSS, Inc.
