[GitHub] [arrow-datafusion] jhorstmann commented on issue #5595: Make median return `null` on empty input rather than error

jhorstmann commented on issue #5595:
URL: https://github.com/apache/arrow-datafusion/issues/5595#issuecomment-1470266735

   The corresponding postgres syntax would be
   
   ```
   SELECT PERCENTILE_DISC(0.5) WITHIN GROUP (ORDER BY column1) FROM ...
   ```
   
   Which returns NULL on empty inputs.
