title: Alter column ignoring dependent views
body: <p>I have column <code>column</code> with <code>character varying(20)</code> type, i want to increase it to <code>50</code></p>
  
  <pre><code>ALTER TABLE table ALTER COLUMN column TYPE character varying(50);
  </code></pre>
  
  <p>I get an error that <code>view view_name depends on column "column"</code>. I wonder how can i alter column without dropping and recreating about 10 depending views?</p>
