> Push down the predicate through the Window operator.
> In this JIRA, predicates are pushed through Window if and only if the following conditions are satisfied:
> - Predicate involves one and only one column that is part of window partitioning key
> - Window partitioning key is just a sequence of attributeReferences. (i.e., none of them is an expression)
> - Predicate must be deterministic
