You should make sure the worker of interest is actually dead, and you didn't get a SIGUSR1 for some other reason. We could probably use a WaitForBackgroundWorkerTermination(...) to correspond to WaitForBackgroundWorkerStartup(...) . I think you'll probably want to GetBackgroundWorkerPid(...) and examine the returned BgwHandleStatus to see if it's BGWH_STOPPED . If not, keep waiting. You might want a timeout to re-check. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
