    Description

      Repro:

      @Test public void testAggregateGroupSetsRollUp() {
          checkMaterialize(
              "select \"empid\", \"deptno\", count(*) as c, sum(\"empid\") as s from \"emps\" "
                  + "group by \"empid\", \"deptno\"",
              "select count(*) + 1 as c,  \"deptno\" from \"emps\" group by cube(\"empid\",\"deptno\")",
              HR_FKUK_MODEL,
              CalciteAssert.checkResultContains(
                  "EnumerableCalc(expr#0..2=[{inputs}], expr#3=[1], "
                      + "expr#4=[+($t2, $t3)], C=[$t4], deptno=[$t1])\n"
                      + "  EnumerableAggregate(group=[{0, 1}], groups=[[{0, 1}, {0}, {1}, {}]], agg#0=[$SUM0($2)])\n"
                      + "    EnumerableTableScan(table=[[hr, m0]])"));
        }
      

      Note that if we change sum(\"empid\") to sum("salary"), it can materialize successfully.
