Description (last modified by Mariusz Felisiak)

I think we should raise NotSupportedError when distinct() is used with values() (or values_list()) on ordered queryset and a list of fields in values() doesn't contain all fields from ORDER BY. It cannot return correct result because columns from ORDER BY clause must be included in SELECT.
