Install PostgreSQL 9.4 with Homebrew

Homebrew is a great tool on Mac to install 3rd-party softwares and unix softwares like libxml2, MySQL, Redis, etc. Today let’s install PostgreSQL 9.4 with it.

1. First, install it with Homebrew command:

    brew install homebrew/versions/postgresql94
   

2. And then, start postgresql service with following command:

    brew services start homebrew/versions/postgresql94
   

   This command will make sure postgresql is running every time you restart your computer. If you just want to start it one time, you could try command: postgres -D /usr/local/var/postgres

3. Last thing you need to do is to create a superuser postgres:

    createuser -d -a -s -P postgres
   

   After entering your password, you have a running postgresql now.
