Yes, it does: it lets users tell the difference between exit due to a SIGQUIT and a crash of their own backend. Admittedly, if we crash trying to send the message, then we're not better off. But since that happens only very rarely, I do not think it's a reasonable tradeoff to never send it at all. regards, tom lane
