title: How to use Lowercase function in Sequelize Postgres
body: <p>I am trying to use the lowercase function to do string searching in Sequelize.
  I manage to do it using the ilike. 
  My question is how to use the lowercase function in this scenario?</p>
  
  <p>The <code>findAll</code> using ilike is as following:</p>
  
  <pre><code>Db.models.Person.findAll(where: {firstName: {$ilike: `somename`}});
  </code></pre>
  
  <p>How do I change it to <code>lower(firstname) = lower('somename');</code></p>
