Before this commit, we separate view query's targetlist into pure_vars and no_pure_vars. This is used to match sub expression for Greedy Algorithm with special order. However, we could combine all that expression into one list expcet those have no vars. The more complex expression is, the higher order is. And pure vars is guaranteed to be later in order. Fix some fields lost of TargetEntry by the way. Authored-by: Zhang Mingli [email protected]
