Well, you'd have to use the same cheat that's used for selectivity
estimation functions, triggers, I/O functions and everything else that
deals in internal datatypes: declare the function as taking and
returning OPAQUE. This is moderately annoying but I don't think
there's anything really wrong with it in practice.
