Hm, I suddenly have a theory. Do you guys use LISTEN/NOTIFY in the databases that are exhibiting the problem? Is it possible that the backends that aren't cooperating have not done anything since they last received a NOTIFY? (That would imply that the connected frontend didn't issue any SQL commands in response to the notification.) regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
