title: Integer out of range in PostgreSQL database
body: <p>I'm trying to save a number representing the length of a file (4825733517).  The column is set to type integer.  I don't have any validations or restrictions set.</p>
  
  <pre><code>RangeError: 4825733517 is out of range for ActiveRecord::ConnectionAdapters::PostgreSQL::OID::Integer with limit 4
  </code></pre>
  
  <p>Should I be using some other column type for this value?  (on rails 4.2.4)</p>
