Check that and copy it to either `config/dev.secret.exs` or `config/prod.secret.exs`. It will also create a `config/setup_db.psql`, which you should run as the PostgreSQL superuser (i.e., `sudo -u postgres psql -f config/setup_db.psql`).

PostgreSQL superuser privileges are only needed for this step.
