Attached is the patch.
Your fix looks like a bad idea to me. If the shared memory area does not exist after an exception occurred the process should be able to re-attach to the shared memory area if it exists or create a new one if that's not the case. That should not be a one-time execution. -- Michael -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
