We've been through this before. That is not an acceptable substitute because there's a race condition: a new child might have been launched but not yet acquired the lock. We need the lock to actually be inherited across the fork/exec so there is no window where it's not held. 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
