I think that this is likely to be a useful area to work on, but I
wonder: can you suggest a useful test-case or benchmark to show the
advantages of the patch you posted? You mention a testcase already,
but it's a little short on details. I think it's always a good idea to
start with that when pursuing a performance feature.
Have you thought about things like specialized prefetching for nested
loop joins?
