Hi,

This patch is marked as RFC since September. Since then there was no
discussion on this thread, but Andrew proposed an alternative approach
based on window functions in a separate thread [1] (both for this and
for the WITH TIES case).

I'll set this patch back to "needs review" - at this point we need to
decide which of the approaches is the right one.

regards
