   `ModuleNotFoundError: No module named 'postgresql'` means your celery backend is misconfigured.  I have checked celery backend config https://docs.celeryproject.org/en/latest/userguide/configuration.html#conf-database-result-backend and your latest superset_config.py file and found smth. See an example from documentation:
   ```
   # postgresql
   result_backend = 'db+postgresql://scott:tiger@localhost/mydatabase'
   ```
   I guess you should update your config with 
   `CELERY_RESULT_BACKEND = "db+postgresql+psycopg2://matteo:matteo@127.0.0.1:5432/superset_loc"` or `CELERY_RESULT_BACKEND = "db+postgresql://matteo:matteo@127.0.0.1:5432/superset_loc"` and re-run celery.
   
   In my 1st example I have also different connection strings for:
   ```
   CELERY_RESULT_BACKEND = 'db+mysql://superset:passsssword@localhost/superset'
   SQLALCHEMY_DATABASE_URI = 'mysql://superset:passsssword@localhost/superset'
   ```
