Review comment:
Moved testcase. I decided to remove the push filter past project rule from
TC. It was causing too many side-effects (plan patterns breaking etc.).
Moreover, it may not be very useful from a cost perspective. We can
re-introduce it if it were to be applied in a cost-based manner (via Volcano
planner).
