You could presumably drop the ones in the public schema.  Probably those
are leftover from ancient history when these things were not getting
created in pg_catalog.

DROP FUNCTION (as a superuser) would be the safest route.  I'm pretty
sure the dependency system would prevent you from dropping the wrong
ones (the ones the language definitions are actually using); though
you might want to verify that in a scratch copy before you do it in
the production database.
