No.
We are trying to get 9.3 out the door, not undertake design, coding,
and testing of entirely new behaviors which will have complex
performance tradeoffs. This sounds like a great project for early in
the 9.4 development cycle, but it's way too late to try to do it now.
(At least if you'd like to ship 9.3 this year. If we're going to
re-open 9.3 for this kind of development, I have some planner fixes
I need to make ...)
