In v17 timeout is in integer milliseconds. I guess one of us misunderstand the other:( and I do didn't check the code very carefully. Acutally I meant the "return value" rather than function argument. IIUC the current return value is void per below statement. >> + <returnvalue>void</returnvalue> If so, when users call pg_wal_replay_wait, they can get informed when the wal is replaied to the target_lsn, but they can't know how long time it waits unless they check it in application side, I think such information will be useful for monitor purpose sometimes. select pg_wal_replay_wait(lsn, 1000); may just take 1ms in fact, in this case, I want this function return 1. -- Best Regards Andy Fan
