title: Postgresql date format error
body: <p>I'm having problems when changing the date format for the datepicker.
  I want to have the 'dd/mm/yyyy/ date format but postgres throws me this error:</p>
  
  <pre><code>ActiveRecord::StatementInvalid - PG::DatetimeFieldOverflow: ERROR:  date/time field value out of range: "16/07/2014"
  Perhaps you need a different "datestyle" setting.
  </code></pre>
  
  <p>because of its american way of saving the date format.</p>
