Review comment:
I looked at this today and it's not as straightforward a port as I
thought. The exec plan drops the fragment information for the most part. I'll
try and take a more comprehensive stab at this tomorrow. Worst case I don't
think it will break things if we filter & project twice and the ExecPlan may
not be where we want to do this kind of optimization.
