That's a pretty neat one-liner. However... in my view, the real cost of rules is that they are hard to support as we add new features to SQL. I believe we already decided to punt on making them work with CTEs... and maybe one other case? I don't really remember the details any more, but presumably this will come up again with MERGE, and perhaps other cases... -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
