title: JSON as attribute in sequlize not working for Postgres
body: <p>my query is to fetch data from a table according to JSON</p>
  
  <pre><code>var jsondata="{'job_media','job_quote','job_invoice', 'job_client','created_by', 'job_status', 'job_source', 'job_job_template_name', 'job_job_template_data'}";
  Jobs.findOne({
      attributes: [jsondata],
      where: { job_id: id}
    });
  </code></pre>
  
  <p>But it's not working, we can change JSON data in any style but should be JSON.</p>
