   > Work fine after modify postgres db engine, and timezone offset problem in explore solved. Steps with docker-compose instance(version=1.3.1).
   > 
   > ```shell
   > docker exec -it superset_app /bin/bash
   > apt-get update
   > apt-get install vim
   > vim /app/superset/db_engine_specs/postgres.py 
   > # delete line 171 (cursor.tzinfo_factory = FixedOffsetTimezone)
   > exit
   > # back to host machine
   > docker-compose -f docker-compose-non-dev.yml restart
   > ```

   > [psycopg 2.9 release note](https://www.psycopg.org/docs/news.html#what-s-new-in-psycopg-2-9) psycopg2 updated to use `datetime.timezone` as `tz` property of datetime object, we do not need `pytz._FixedOffset` any more.
   
   
   This solution works for me.
