It runs on nearly any operating system including Linux, Unix, and Windows. Put simply, it is a database that allows you to relate one piece of data to another (thus, “relational”). PostgreSQL is an ACID-compliant Object Relational Database Management System, or ORDBMS (quite a mouthful!). Know how to use both command-line and UI tools to manage your database.Know how to create and manage databases and users.Have a running PostgreSQL 9.5.4 instance.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. Postgres is smart enough to see that I'm logged in as the postgres user, and it lets me right in. Note that I'm doing all this without specifying the database user I want to connect as. Next, you can connect to this new test database with the following command: First, the command to create a new Postgres database named test: (As you can see from these commands, the root directory of the Postgres server on my Mac computer is /usr/local/pgsql.)īonus: How to create and connect to a Postgresql databaseĪs a quick bonus (and a reminder to myself), here's how you create and then use a Postgres database. usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start Here's how I include the Postgres bin directory in my path:Īnd here's the command I use to start the Postgres server: Once you're logged in as the postgres user, you just need to make sure your path includes the Postgres bin directory, and then issue the command to start Postgres. So, Step 1 of starting Postgres is to open a Terminal window, and switch over to that user account, like this:Īfter issuing this command, you'll also need to provide the password for the "postgres" user. After I finished that installation, a "postgres" user account was created on my Mac during the installation process. So, to keep that from happening again, here's a quick tip on how to start Postgres (Postgresql) on a Mac OS X computer.Ī long time ago I followed this Apple tutorial on how to install Postgress on a Mac. Wow, it had been a long time since I last started Postgres on my Mac computer ( a MacBook Pro, to be specific), and it took almost almost 20 minutes to remember how to do it. ![]()
