How does exiting before they're dead help? They're still going to be attached to shared memeory and thus prevent a restart. I don't think hiding the problem by exiting the postmaster helps at all. I don't think it's our job to protect against processes stuck in the kernel. If that happens something seriously has gone wrong, and we shouldn't just continue without making that visible. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
