I don't like it.  As given, it inserts default values into the query
at parse time, whereas this must not be done until planning time.
(Otherwise the defaults sneak into stored rules, and if you change
defaults with ALTER TABLE you will get unexpected results.)  The
correct (and actually easier) way is to simply drop the defaulted column
out of the analyzed query altogether.

This is not Pavlo's fault exactly, since he copied the way we used
to do it in 7.1 ... but the patch must be updated to follow 7.2
practice.

Another problem: no copy/equal/outfuncs support for the added node type.

Stylistic issue: we should discourage people from putting their initials
on every bit of code they touch.  The code will soon be unreadable if
such becomes common practice.
