title: Ecto Postgres install error password authentication failed
body: <p>I created a phoenix project from the hello example using digital ocean.  I entered the username and password from the etc/motd.tail file.  I keep getting the error message below.  I am a beginner and for some reason I just cannot get ecto to install correctly.</p>
  
  <p>** (Mix) The database for Hello.Repo couldn't be created, reason given: psql: FATAL:  password authentication failed for user "elixir"
  FATAL:  password authentication failed for user "elixir"</p>
  
  <p>You can use the following Postgress database credentials:
    * User: elixir
    * Pass:  ***</p>
  
  <p>install.  Any help would be appreciated. </p>
