Onder Kalaci	498ac80d8b	Add window function support for SUBQUERY PUSHDOWN and INSERT INTO SELECT This commit provides the support for window functions in subquery and insert into select queries. Note that our support for window functions is still limited because it must have a partition by clause on the distribution key. This commit makes changes in the files insert_select_planner and multi_logical_planner. The required tests are also added with files multi_subquery_window_functions.out and multi_insert_select_window.out.	2017-10-04 15:33:07 +03:00
