Not sure if you really want to go there, but I do agree with you and there's a thread from a few years back about something similar: http://www.postgresql.org/message-id/flat/20110112142345.ga4...@tamriel.snowman.net Included in that thread is a patch, which likely requires some dusting off, to add exactly that ability.
