That doesn't make sense, since if I delete the entry from pg_proc and then create the funtion, everything works fine. Eg: delete from pg_proc whete proname = 'funcname'; create function pg_catalog.funcname(); > This behavior is not really open to negotiation; not only on > grounds of speed, but on grounds of circularity.
