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. regards, tom lane
