I had never used a Mac before as I considered them overpriced relative to a desktop I could setup with Linux. But since that’s what I was given, that’s what I was used. One of the first things I had to do is figure out how to get Postgres up and running.
Eventually, I had to learn a good way to upgrade it as well. At my first job, I found that using Heroku’s Postgres app. At my next job, I used the homebrew package manager since that’s how our team used it.
So what follows is a mini-guide I put together on how to install postgresql on Mac as well as how to upgrade it with homebrew.
Now if you want to use Heroku’s Postgres app, it’s pretty easy and is a good alternative to homebrew.
Installing Postgres via Homebrew
This guide assumes that you have homebrew installed. If you don’t, you can find some instructions here.
Once you do that, all you have to do is issue the following command in your terminal:
$ brew install postgres
It should install the latest version of Postgres available via Homebrew. Pretty easy, right? https://sphereyellow448.weebly.com/blog/grab-app-mac-os.
Upgrading Postgres via Homebrew
Ok, so let’s say you have to upgrade postgres. I had to follow these steps when I was upgrading to Postgres 9.6
Step 1 – Turn off Postgres
The first step is to turn off the postgres service if it’s running in the background.
$ brew services stop postgresql
Step 2 – Upgrade
Next, we’ll use homebrew to upgrade it to the latest version.
$ brew update && brew upgrade postgresql
Step 3 – Switch
Finally, we’ll switch to the new version using the following command.
brew switch 9.6.1
You’ll see output like the following:

Now to ensure postgres starts automatically every time you start your Mac, you’ll need to do some extra setup.

Step A – You’ll need to setup LaunchAgents![]()
Create the directory ~/Library/LaunchAgents if it doesn’t exist already.
How To Uninstall PostgresqlStep B – Copy the plist file to ~/Library/LaunchAgents/
Use mail.com addresses on mail app mac os. There’s a plist file that comes with the postgres install from homebrew.
When upgrading to 9.6.2, my plist was at /usr/local/Cellar/postgresql/9.6.2/homebrew.mxcl.postgresql.plist.
Copy the plist file to the LaunchAgents directory.
cp /usr/local/Cellar/postgresql/9.3.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
Step C – Load launchctl
Now use launchctl to load the file using this command:
$ launchctl load -w homebrew.mxcl.postgresql.plist
You can also use a ruby gem called lunchy. I haven’t tried it but this blog post describes the process.
