Hello I am looking on this patch
http://www.postgresql.org/message-id/525fe206.6000...@dalibo.com a) pg_sleep_for - no objection - it is simple and secure b) pg_sleep_until I am not sure - maybe this implementation is too simply. I see two possible risk where it should not work as users can expect a) what will be expected behave whem time is changed - CET/CEST ? b) what will be expected behave when board clock is not accurate and it is periodically fixed (by NTP) - isn't better to sleep only few seconds and recalculate sleeping interval? Regards Pavel
