You might be wondering why there's a need for another setup guide for Postgres in the first place, since there are a few across the web. I found many tutorials and guides on how to set it up, but found most of them to be unclear and outdated, based on old PostgreSQL versions.

If you spot any flaws in this guide, a comment below would be very helpful to keep it up to date for other developers. I recommend Homebrew for installing and managing applications on MacOS.

Next, let's go through the steps of setting up a database that can be used for one of your applications. Make sure the Postgre server is started first, then type these commands in the command line to create and remove a database:.
You can also connect to databases to execute SQL statements. Either use the psql command, or specify a database such as the default postgres database to connect:. In the psql shell, you can create and drop databases as well:. Your will see any new databases listed, as well as two default databases that come with postgreSQL called template0 and template1.
The templates should remain in your database list even if you aren't using them, as they may be useful later. You might be wondering why there's a need for another setup guide for MongoDB in the first place, since there are a few across the web.
