That patch already happened on the list, and it wasn't a win in many cases. I'm not sure it should be proposed independently of this one.

I don't have an archive link at hand atm, but I could produce one later. -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
