title: FATAL: Peer authentication failed for user "shop"
body: <p>What I did:</p>
  
  <pre><code>sudo -u postgres psql
  CREATE ROLE shop CREATEDB LOGIN PASSWORD 'kurt1245';
  </code></pre>
  
  <p>Then I cloned a repository from GitHub (a rails application which uses pg), <code>bundle install</code>, edit <code>database.yml</code> to write my password and now after <code>rake db:create</code> (also <code>setup</code> and <code>migrate</code>) doesn't work.</p>
  
  <p><code>database.yml</code>:</p>
  
  <p><code>development:
    adapter: postgresql
    encoding: unicode
    database: shop_development
    pool: 5
    username: shop
    password: kurt1245
  test:
    adapter: postgresql
    encoding: unicode
    database: shop_test
    pool: 5
    username: shop
    password: kurt1245
  </code></p>
