   Same issue here. Docker instance had no issues with connecting to local 
postgres db but my local install of apache-superset installed via pip in venv 
yielded the following error despite successful connection w/ postgresql 
instance:
   
       DB engine Error
       postgresql error: '>=' not supported between instances of 
'datetime.timedelta' and 'int'
       
       See more
   
   And here is the query (very simple w/o any relational operators):
   
   ```sql
   SELECT *
   FROM pulse_ox_moving_average;
   ```
   Here are the only packages installed in the venv, apart from 
apache-superset, I installed psycopg2 and that is all.

   `
   I do have one timestamped column, but this was a non-issue w/ the 
docker-compose install.
