"Working"? What you submitted was a self-acknowledged crude hack,
which was shortly shown to have several major problems; a quick look
in the archives suggests
* fails on subplans, and possibly other things that ruleutils.c
doesn't support well
* not at all clear what to do with aliased column names
* requires custom support in each PL, only one of which was
actually implemented
and there are probably more (I didn't reread the whole thread). The
fact that I suggested a possible avenue to fixing some of those problems
doesn't make it my responsibility to fix them ... especially not if I
don't particularly approve of the hack in the first place. Even with
all this fixed it would be a dead-end feature, but we'd be stuck with
supporting it forever. You should be happy that I was willing to hold
still for accepting the patch if the problems got fixed.
