[GitHub] [arrow-datafusion] andygrove commented on issue #3786: Optimizer adds redundant projections on casts with confusing alias

andygrove commented on issue #3786:
URL: https://github.com/apache/arrow-datafusion/issues/3786#issuecomment-1281509940

   Another example:
   
   ```
   Projection: household_demographics.hd_vehicle_count > Int32(0) AS household_demographics.hd_vehicle_count > Int32(0)Int32(0)household_demographics.hd_vehicle_count
   ```
   
   The alias name should just be:
   
   ```
   household_demographics.hd_vehicle_count > Int32(0)
   ```
   
   and not
   
   ```
   household_demographics.hd_vehicle_count > Int32(0)Int32(0)household_demographics.hd_vehicle_count
   ```
