I think it'd be a mistake to expend much effort on this issue in JDBC
right now.  We will eventually implement SQL92-compliant schemas in the
backend, and once that happens it'll be possible to do something
reasonable with the catalog metadata routines in JDBC.  If you try
to make a half-usable implementation now, you'll just create backwards-
compatibility issues for the real implementation later.  So my counsel
is: acknowledge that it's broken, but ignore it for now.

When is "eventually"?  Possibly 7.3, but I can't promise anything...
