title: How to log in as "postgres" user with PostgreSQL 8.4.7 on Windows 7
body: <p>I installed PostgreSQL on my windows 7 desktop.</p>
  
  <p>Usually PostgreSQL will create new account on my desktop, but when i want to switch user, there's no user named <code>postgres</code>. Then I checked the user folder in directory "C" and there's already a folder user named <code>postgres</code>.</p>
  
  <p>But why can't I log in into my desktop using <code>postgres</code> account?</p>
