A > possibly good way to do this is to SIGSTOP the backend(s). This is a far more common and likely problem than the server crash scenario. I've had servers go unresponsive under load before. Took the load away and they came back, but the way the app responded has not always been optimal. Many apps get jammed up from something like this and require the app servers to be restarted. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
