What makes you think there is a single "correct" return value? If
multiple rows are being inserted/updated it's entirely possible that
some of them will be in different child partitions.
If we were interested in changing the status behavior, I'd be inclined
to think about something like adding up the rowcounts from all the
replacement queries that're of the same type as the original. However,
I have some recollection that this was proposed and shot down in the
discussions that led to the current solution --- as a counterexample
consider an ON INSERT DO ALSO that inserts rows into a logging table.
This should be hidden from the user but would not be if we added its
effects to the result tag.
