Now that you mention it, didn't we solve a similar problem by exploiting the behavior where CreateProcess creates a process but doesn't start it running? I'm envisioning * Create child process in suspended state * Assign it ownership of a lock (can we do that?) * Set it running If the postmaster crashes between steps 1 and 2, then the zombie process doesn't hold a lock, but it will never do anything so it doesn't matter. OTOH, if the postmaster crashes between steps 2 and 3, there's probably no way to restart your database except to reboot ... regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
