I'm strictly talking about a setting that would only be used on systems
being used to port from databases that fold to uppercase like Oracle.  I
wouldn't want any changes that affected folks who didn't turn on the
option, only those who did.

For what I need, a hack that basically folded to upper everything that
didn't start with pg_ would work fine.  Now that catalogs live in the
pg_catalog schema, I could just treat anything in the pg_catalog to be
fold to lower, while everything else would fold to upper.

Would that be an acceptable kludge, or would we want the catalog to be
folded to upper in those cases too?  I can't see a reason for doing it
that way, since I doubt anyone porting Oracle sql code is gonna be messing
with the catalogs as well.
