True. Not sure if I ever built one, but when playing around.

To the point that I am not seing the problem right now. I am not
proposing to get rid of statically assigned oids in pg_type et al.. The
references to procs mostly seem to be typed 'regproc' so there aren't
many references to function's oids. There's a few procs that are
involved in bootstraping, those likely would need to keep a fixed oid,
but that doesn't sound problematic to me.

Not sure. Any such infrastructure should have support for filling in
defaults for things that don't need to be specified - imo generating an
oid for that sounds like it would fit in there. Doesn't - and possibly
shouldn't - be the same commit though.
