You also specified the -P flag, which means you will be prompted to enter a password for your new role. The -d flag gave the role the permission to create new databases. In this command, you used createuser to create a role named appname. To create a new role, run the following command, replacing appname with whatever name you’d like to give the role: createuser -P -d appname In order to keep these superuser privileges separate from the database instance you use for your Rails application, in this step you will create a new role with less access. When starting PostgreSQL with Homebrew, you will automatically have a superuser role created with your macOS username. In PostgreSQL, roles can be used to organize permissions and authorization. Step 2 - Creating a Database Role for Your Application

Once PostgreSQL is installed, the next step is to create a role that your Rails application will use later to create your database. You will get the following output: Output To start the service and enable it to start at login, run the following: brew services start to make sure the installation was successful: postgres -V Then, apply the changes you made to your ~/.bash_profile file to your current shell session: source ~/.bash_profile Next, include the PostgreSQL binary in your PATH variable in order to access the PostgreSQL command line tools, making sure to replace the 10 with the version number you are using: echo 'export > ~/.bash_profile You can find the available packages at the Homebrew website.

However, for highly complex applications that need more reliable data integrity and programmatic extensibility, a PostgreSQL database will be a more robust and flexible choice. SQLite is a lightweight, portable, and user-friendly relational database that performs especially well in low-memory environments, and will work well in many cases. When using the Ruby on Rails web framework, your application is set up by default to use SQLite as a database. You will install and configure PostgreSQL, and then test your setup by creating a Rails application that uses PostgreSQL as its database server. In this tutorial, you will set up a Ruby on Rails development environment connected to a PostgreSQL database on a local macOS machine.
