Sure. It'll be a bit faster. I just don't see the peformance increase in not that common situations being worth the price we'll pay in development, code review, debugging and then maintaining some nontrivial code. If this were likely to be a 15 line patch, I'd think differently. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
