Understanding the existing databases

Once the database has been launched, we can connect to PostgreSQL using a psql frontend:

psql postgres

Ideally, you connect to a database called postgres, which can be found in any database instance. Some systems don't encourage people to log in as a postgres user. Therefore, you might want to use sudo here as well to log in to PostgreSQL. If this works for you, you can make PostgreSQL display a list of existing databases, where \l will do the job:

postgres=# \x
Expanded display is on.
postgres=# \l
