      # database name you want. Use `bin/rails db:prepare` to create the database.

      # Example:
      #
      #  development:
      #    <<: *default
      #    host: db
      #    username: postgres
      #    password: postgres
      #    database: myapp_development

    # Add "forwardPorts": ["5432"] to **devcontainer.json** to forward PostgreSQL locally.
    # (Adding the "ports" property to this file will not forward from a Codespace.)
