PostgreSQL is an ACID-compliant Object Relational Database Management System, or ORDBMS (quite a mouthful!). You will need at least a basic level of comfort using the command line using either the MacOSX built-in terminal, iTerm2, Zsh, or something similar.
This tutorial will teach you how to set up, configure, and use PostgreSQL on MacOSX 10.7 (Lion) and above. If you’re here reading this tutorial, hopefully, you are trying to do the same!
The other day I began a new Node.js project and wanted to use PostgreSQL as my database backend.
