As penance, here's a comment that I think is actually correct: sending SIGINT to the postmaster will make it turn around and send SIGTERM to all the backends. So there are two different explanations for the backends giving the "administrator command" error: either some outside force sent them SIGTERM directly, or some outside force sent the postmaster SIGINT. The SIGINT-the-postmaster theory is the more likely, I suspect, and that again could be associated with having carelessly left the postmaster attached to one's terminal. In any case, the first thing to do is look in the postmaster log and see if you see a message about "received fast shutdown request", which would be proof one way or the other. regards, tom lane
