title: Postgres 9.1 - can't create extension for adminpack to work with pgadmin
body: <p>I'm working on a Rails app and have successfully loaded postgresql9.1 on my macX.  Rails works fine with postgres, but now want to fully use pgadmin3 to update tables.</p>
  
  <p>Pgadmin3 indicates I need to add adminpack -- the file is already in the postgres dir on  my mac.  Postgres guide (and the command line) say that a "CREATE EXTENSION --adminpack" command is needed.  I've tried many different approaches and can't figure it out.  I'm first time postgres user so any help would be a life saver!</p>
  
  <p>The terminal command/response is below:</p>
  
  <blockquote>
    <p>$ CREATE EXTENSION adminpack--1.0<br>
    -bash: CREATE: command not found</p>
  </blockquote>
  
  <p>Everything else with the postgres db/admin/rails seems to be working well.</p>
