I think what was meant was plans of my colleague Dmitry Ivanov to
implement partition-pruning. I've just spoke with Dmitry about this
matter. Unless there is anyone else who is already working on this
optimization we would like to work on it together. Unfortunately there
is no patch or design discussion of partition-pruning on this
commitfest.
