I wonder if we should have a different mode of operation that only attempted the truncate (say VACUUM TRUNCATE), optionally being non-conditional about obtaining the required lock. That said, I wonder even more whether any such hacks are still needed after the visilibity map that changed the landscape for vacuum so dramatically. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
