    Description

      We want to be able to specify in some way (say a plan index) the plan alternative we want to execute. Under normal circumstances we want naturally the best plan, but with for debugging and correctness testing we want to execute say plan alternative #10 which would be amongst the rejected plans.

      One way to achieve this would be to introduce a test-only query knob with some integer value specifying the index of the plan alternative.
