Can't get excited about that.  Will you also have asserts to complain
if the wrong combinations of tuples are supplied for the other cases?
Is this really likely to catch anything?  It's not like this function
is called from a variety of places.

While I was applying the patch I considered changing the 
        if (LocTriggerData.tg_trigtuple != NULL)
        if ((event->ate_event & TRIGGER_EVENT_OPMASK) == TRIGGER_EVENT_UPDATE)
but this didn't seem to be an improvement on the whole, as it effectively
provides two ways to get it wrong (wrong tuple args OR wrong event)
instead of only one.  I think driving the setup of the tuple fields
entirely off the provided tuple args is logically cleaner.
