Conflicts may arise between the Zibawa and Grafana database. If you find that newly created users cannot log in to Grafana, this may be because the userID of Zibawa is already occupied on the Grafana database. A work around is to move forward the user ID counter of the Zibawa database.
\connect zibawadb ALTER SEQUENCE auth_user_id_seq RESTART WITH 50;

If you followed the steps above:
cd workspace/virtualenv/pgadmin source bin/activate python lib/python2.7/site-packages/pgadmin4/pgAdmin4.py
Then access on http://localhost:5050
