title: SQLAlchemy: how to filter on PgArray column types?
body: <p>In pure postgres we can write:</p>
  
  <pre class="lang-sql prettyprint-override"><code>SELECT * FROM my_table WHERE 10000 = ANY (array_field);
  </code></pre>
  
  <p>or</p>
  
  <pre class="lang-sql prettyprint-override"><code>SELECT * FROM my_table WHERE 10000 = ALL (array_field);
  </code></pre>
  
  <p>How to do the same with the help of sqlalchemy without raw sql?</p>
