   I think column resolution should only look at one level, to make the behavior simple and predictable. I tried it on pgsql and it fails as well:
   ```
   create table t(i int);
   select id from (select i as id, i as ID from t) sub;
   ERROR: column reference "id" is ambiguous Position: 8
   ```
