   This pr #7494 prohibits the distinct semantics that may appear in aggregate functions. 
   For example, ```select count(distinct c1) from table1```
   
   But there is another situation that is distinct in the select item. 
   For example, ```select distinct c1, c2 from table```
   And this situation can actually be supported. It is equivalent to select c1, c2 from table group by c1, c2.
   Can you help us add this part of the changes in the follow-up pr?
