Yeah, that won't be a bad idea especially because the patch being
discussed in the thread you referred is still in an exploratory phase.
I haven't tested or done a detailed review but I feel there shouldn't
be many problems if we agree on the approach.

Thomas/others, do you have objections to proceeding here? It shouldn't
be a big problem to change the code in this area even if we get the
shared relation size stuff in.
