title: Delete all table without dropping database in postgres in django dbshell in one command?
body: <p>I tried this ..</p>
  
  <pre><code> select 'drop table if exists "' || tablename || '" cascade;' 
  from pg_tables
   where schemaname = 'public';
  </code></pre>
  
  <p>but doesn't seems to work out for one command?</p>
