Uh-huh, so there you have it.  These must be leftovers from some
pre-extension incarnation of plpython that was never cleaned up
properly.  Try

DROP FUNCTION pg_catalog.plpython_call_handler();
DROP FUNCTION pg_catalog.plpython_inline_handler(internal);
DROP FUNCTION pg_catalog.plpython_validator(oid);

It'll be interesting to see if there are any dependencies.
