I'd have to agree.

You might be referring to pg_shadow.usecatupd, but that only covers direct
catalog updates. The postgres -O switch allows system schema changes, that
doesn't apply either.

Anyway, shouldn't you be able to do CREATE FUNCTION xxx (...) LANGUAGE
'internal'; to recreate it? (And that wouldn't actually require things
like oideq to be in pg_proc, would it?)
