Once postgres is setup, before this can be run in production:

• Run /usr/local/Cellar/postgresql/11.3//bin/createuser -s postgres to create a user called postgres
  • Only need to do this once per computer, and the username can be whatever you want
• Change username in config/database.yml to the username that you created in the above step
• Create a .env file with your HELLO_APP_DATABASE_PASSWORD. In order to create a random password, you can run rails secret.
• Run bundle exec rake db:create:all to create the databases locally.
• Don't forget to run heroku run rails db:migrate for migrating a new database on heroku!
