title: How to remove a postgresql user
body: <p>I followed <a href="http://musings.tinbrain.net/simple-django-deploy/" rel="nofollow noreferrer">this tutorial</a> and made a typo where I was supposed to create a user for my django apps to connect as;</p>
  
  <p>I was supposed to run <code>su - postgres -c "createuser www-data -P"</code> but I ran <code>su - postgres -c "createuser www-dtata -P"</code>.</p>
  
  <p>I dont want to proceed until I remove that user, which I don't know the command for. I found and tried <code>DROP USER</code> after searching around, but the terminal returned <code>-su: DROP: command not found</code>.</p>
