It seems like the COLUMN_UDT_USAGE view ought to handle this ...
except perhaps that COLUMN_UDT_USAGE for some reason substitutes the
underlying type if the column type is a domain.  I can't see the
justification for that --- Peter, what part of the spec led you to do
it that way?  There is probably more than one way to define the spec's
notion of "user-defined types" in terms of Postgres notions, but I
don't see where you got this particular definition.
