FWIW, I'm +1 on the cleaner design you suggested. While I understand the concerns of adding features/API this late; as a user, I'd rather not wait another year to have these available in core(yes, I know alternative measures would exist if it did not make it into core, but the convenience of having it there would certainly be nice). That is, I really like the waiting variant. It is something that I would use. The lack thereof(IIRC) in the current contrib implementation is something that I have recently lamented about. I understand that "want" is not a reason to compromise the feature freeze, so I hope the legal concerns Tom mentions will be enough. =) ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
