   I don't think this is a bug. Namely I think the query as you have written it should fail.
   
   The correct (SQL standard) way to write a query that refers to the `"Level"` column I think is:
   
   ```sql
   select * from table1 where "Level"='INFO'
   ```
   
   Which is consistent with what postgres does.
