Yes, it is key to have DEFAULT working before we change this, and it is
in CVS now, committed a week or two ago.

Peter, are you saying you don't want to require all columns to be
specified when INSERT doesn't list the columns?

Yes, that's what I'm saying.  Too much breakage and annoyance potential in

OK, how about a NOTICE stating that the missing columns were filled in
with defaults?

Yuck. There is a short path from that to rejecting the insert, but
printing the entire insert statement which would have been acceptable in
the error message ;)
