How to Install PostgreSQL on macOS Catalina

Hello everyone, welcome to another Hackintosh tutorial. In this article, I will try to install PostgreSQL server on my macOS Catalina Hackintosh. I haven’t done this before so let’s find out if this is work or not. Installing PostgreSQL on macOS is pretty similar to the Linux installation. I am going to use Homebrew to get the PostgreSQL server up and running.

Steps to Install PostgreSQL Server on macOS Catalina

Step 1. Install Homebrew

Open Terminal and then paste this command to install Homebrew. Homebrew is a clever application that will help us to install almost anything on macOS.

/bin/bash -c "$(curl -fsSL"

Press Enter to start the installation.

This process will download some files from the internet. So, make sure you are connected to the internet during the installation. Make sure the installation finish successfully as follow:

Step 2. Install PostgreSQL using Homebrew

Now lets install PostgreSQL with this command

brew update
brew install postgresql

Again, this process will download files from the internet. Wait until the installation process completes.

Now lets check the PostgreSQL version

postgres --version


At this point, the PostgreSQL Server is installed.

Step 3. Configure the PostgreSQL Server

Now we are going to initialise the database.

initdb /usr/local/var/postgres

As you can see, the command result in error

initdb: error: directory "/usr/local/var/postgres" exists but is not empty. If you want to create a new database system, either remove or empty the directory "/usr/local/var/postgres" or run initdb with an argument other than "/usr/local/var/postgres".

That is fine. This means that we already have the database in the directory. This process was automatically created a new database called “postgres”.

Start/Stop PostgreSQL Database Server

Use the following command to start and stop the server:

pg_ctl -D /usr/local/var/postgres start
pg_ctl -D /usr/local/var/postgres stop

Connect to the database

To connect to the database, use psql command. For example:

psql postgres

The command will connect to the database “postgres“.

That’s it. We have just installed PostgreSQL Server on macOS Catalina. I have tested this on my Intel Hackintosh system. Next time, I will try it on my AMD Hackintosh.
