Hello [~julianhyde],
I updated PR. I added test cases for cast in
{{AggregateExpandDistinctAggregatesRule}} and {{AggregateReduceFunctionsRule}}.
I don't know how I can check cast null literal in {{AggregateValuesRule}}
because the rule works with result null literal and I get
{noformat}LogicalValues(tuples=[[{ 0, null }]]){noformat}in result plan for
{{select count(*), sum(empno) from emp where false}}
