Yeah, that's a problem.  New thought: how about we go back more or
less to the original coding, except replacing the second argument
(only) with a Relation?  In other words, callers will pass either a
Relation (which might be a table or foreign table) or a type name.
Not particularly elegant, but no worse than what we had before.
