I was thinking about exactly that case as I went to sleep - especially as it's things like CREATE OR REPLACE VIEW that prevent me from just rewriting the security qual when it's initially added, before storage in the catalogs. I could've sworn discussion around row security in the past concluded that it couldn't be properly done in the rewriter because of an inability to correctly invalidate plans. Searching the archives, though, I don't find anything to support that. I'll just say I'm glad to be wrong, and proceed from there. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
