title: default user of postgres at install
body: <p>I installed Postgres on Windows 7, it only asks me for password not for username so what's the default. It is said here:</p>
  
  <blockquote>
    <p>When Postgres is installed in your account, there is a default user with the same name as the account (login) name</p>
  </blockquote>
  
  <p>It's not crystal clear. Is it the username of my computer account?</p>
