      Description

      With current implementation of MV matching, below case fails

        @Test public void testFilterOnProject() {
          String deduplicated =
              "(select \"empid\", \"deptno\", \"name\", \"salary\", \"commission\"\n"
                  + "from \"emps\"\n"
                  + "group by \"empid\", \"deptno\", \"name\", \"salary\", \"commission\")";
          String mv =
              "select * from\n"
                  + "(select \"deptno\", sum(\"salary\") as \"sum_salary\", sum(\"commission\")\n"
                  + "from " + deduplicated + "\n"
                  + "group by \"deptno\")\n"
                  + "where \"sum_salary\" > 10";
          String query =
              "select * from\n"
                  + "(select \"deptno\", sum(\"salary\") as \"sum_salary\"\n"
                  + "from " + deduplicated + "\n"
                  + "group by \"deptno\")\n"
                  + "where \"sum_salary\" > 10";
          checkMaterialize(mv, query);
        }
      

      Reason:
      After matching of the Aggregates, a compensating Project is added, but afterwards matching of filter fails to handle it.
      This issue proposes to handle such case where query and target are Filters and query has a compensating Project child node
