A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:. - Source: dev.to / 3 months ago

I was using Postgres.app, but of course, you can download it in any way as long as it works. - Source: dev.to / 4 months ago

There are two ways to connect with the Postgres database which can be in the terminal or using a Postgres GUI client app like DBeaver. But first, download the PostgreSQL installer for macOS or Windows, depending on your OS. The setup and installation come with the psql command, a tool shipped with Postgres that allows you to communicate with Postgres through the command line. - Source: dev.to / 6 months ago

6a. Even stricter option is an "append-only" aka "timeseries" schema, which I highly recommend. Can't remember the last time I didn't use one. 7. If you happen to be testing on a Mac, https://postgresapp.com/ is easier than the MacPorts or Homebrew packages. - Source: Hacker News / 7 months ago

And if you're on a Mac, Postgres.app makes it even easier: https://postgresapp.com/. - Source: Hacker News / 12 months ago
