----------------------------------------
Plan changes in bucketsortoptimize_insert_4.q looks correct. I have provided
explanation on RB. I think this patch is ready for review. [~navis] Can you
take another look?

> {{Extract Operator}} has been there for legacy reasons. But there is no
> functionality it provides which cant be provided by {{Select Operator}}
> Instead of having two operators, one being subset of another we should just
> get rid of {{Extract}} and simplify our codebase.
