    # Create the MySQL User change $password to a real password
    mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';

    sudo -u postgres psql -d template1

    # Add a user called gitlab. Change $password to a real password
    template1=# CREATE USER gitlab WITH PASSWORD '$password';

    # Create the GitLab production database & grant all privileges on database
    template1=# CREATE DATABASE gitlabhq_production OWNER gitlab;
