The logic was copied from array_in which does something similar, but AFAIR there's not really any code path which would feed differing input types to the same function call within a single query execution. Still, since it takes only an extra comparison or so to handle the scenario, why not? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
