+## Setting `postgres` user password
+
+By default the `postgres` user is not assigned a password and as a result you can only login to the PostgreSQL server locally. If you wish to login remotely to the PostgreSQL server as the `postgres` user, you will need to assign a password for the user using the `PG_PASSWORD` variable.
