My impression is that Service-startup is rather nondeterministic in aspects of timing. So I would suggest to integrate that sleepy workaround within pg_autovacuum service. Just let it sleep for 'some time' ... maybe even configurable ... before it connects. (recommended default: 180 seconds; NOT microseconds and NOT milliseconds :)) That will not harm anything: on system-startup there is running a lot of rubbish anyway, so it does really not hurt if the first vacuum-run is 3 minutes later (on a usual system starting up it will take 3 minutes anyway before scheduling time-slices for vacuum is really sensible) And really intensly productive servers should not boot anyway. So: nobody gets hurt, and pg_usleep is very well tested. Harald ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
