title: Postgres createuser.exe silent execution from batch script
body: <p>I am finding myself with the issue of needing to execute the postgres createuser.exe from a batch script and cannot get it to stop prompting me with the following:</p>
  
  <p><code>Enter name of role to add:</code></p>
  
  <p>my batch script looks like this:</p>
  
  <p><code>echo calling createuser!
  createuser username %super_user% -s -U Super_Postgres s -q</code></p>
  
  <p>Where %super_user% is a command line argument.  Any help would be greatly appreciated, this is the documentation that I am referring too: postgres</p>
