   ### What problem does this PR solve?
   
   if mv def sql is as following:
   ```sql
   create matrialized view test_mv as 
   select k1, k3, sum(k2), count(k4) from ${tblName} group by k1, k3;
   ```
   if query  are as following, should not use test_mv above
   ```sql
   select count(k1) from agg_use_key_direct;
   
   select sum(k1) from agg_use_key_direct
   
   select avg(k1) from agg_use_key_direct
   ```
   
   the wrong case would happen when in branch-2.1 or `set 
enable_sync_mv_cost_based_rewrite = false;` on branch-3.0 or master, the pr fix 
this
   
   
   if query  are as following with distinct or is `max` or `min`, can use 
test_mv above
   
   ```sql
   select count(distinct k1) from agg_use_key_direct;
   
   select sum(distinct k1) from agg_use_key_direct
   
   select avg(distinct k1) from agg_use_key_direct
   
   select max(k1) from agg_use_key_direct
   
   select min(k1) from agg_use_key_direct
   
   ```
