Installing PostgreSQL on Mac

In this guide, we will show you how to install PostgreSQL on a Mac step by step.

Step 1: Install Homebrew

Homebrew is a package manager for macOS, which simplifies the installation of software like PostgreSQL.

  1. Open the Terminal application on your Mac.
  2. Paste the following command to install Homebrew:
</>
Copy
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Follow the on-screen instructions to complete the installation.

Step 2: Install PostgreSQL

After installing Homebrew, use the following command to install PostgreSQL:

</>
Copy
brew install postgresql

Wait for the installation to complete. PostgreSQL will be installed along with its dependencies.

Step 3: Start PostgreSQL Service

Once installed, you need to start the PostgreSQL service.

</>
Copy
brew services start postgresql

This command ensures that PostgreSQL runs in the background and starts automatically after a system reboot.

Step 4: Verify Installation

  1. To confirm PostgreSQL is installed and running, use the following command:
</>
Copy
psql --version

If installed correctly, this will display the version of PostgreSQL.

Step 5: Access PostgreSQL

You can now use the psql command-line tool to access PostgreSQL:

</>
Copy
psql postgres

This will connect you to the default PostgreSQL database.

Conclusion

By following these steps, you have successfully installed PostgreSQL on your Mac. You can now start using PostgreSQL to manage your databases.
