title: Connecting Apache Superset to an external database
body: <p>I am running apache superset on docker, and I have been trying to connect to an external database(Postgres) using the example link on SQLAlchemy Docs for connecting to a Postgres database (<strong>postgresql://scott:tiger@localhost/mydatabase</strong> // postgresql://username:password@localhost:5433/postgres). However, I have been getting the following error: Connection failed, please check your connection settings. Could someone please help me with this.</p>
