title: How to access tables in other schema in korma?
body: <p>In SQL, accessing tables in other schema is simple:</p>
  
  <pre><code>select * 
  from other_schema.t
  where ...
  </code></pre>
  
  <p>How can I do this in korma? What I actually to do is to access <code>information_schema.tables</code> table. So defining another <code>db</code> by <code>defdb</code> wouldn't be helpful.</p>
  
  <p>I've tried to define the entity, however, failed.</p>
  
  <pre><code>(defentity information_schema.tables)
  </code></pre>
