title: Unique Integrity Error on Email Field (Not User model)
body: <p>I am getting this error when trying to create a <code>Member</code> (<strong>note that this is not the User model</strong>) with an <code>email</code> that already exists:</p>
  <pre><code>duplicate key value violates unique constraint &quot;members_member_email_key&quot;
  DETAIL:  Key (email)=(myemail@gmail.com) already exists.
  </code></pre>
  <p>The <code>email</code> field for the <code>Member</code> model looks like this:</p>
  <pre><code>email = models.EmailField(max_length=255, unique=False, primary_key=False)
  </code></pre>
  <p>Why am I getting this error if <code>unique</code> is set to <code>False</code> and it is not a <code>primary_key</code>? Thanks!</p>
