That's too vague to answer really. My suspicion is that you'd still end
up having to modify the queries, ie hand-factoring the joins, but maybe
you wouldn't need to. You could experiment easily enough; just set up a
toy database with not much data in it and see if you get plans that don't
scan all the partitions.
