title: SQLdelight drop all tables
body: <p>I'm using SQLDelight in the Kotlin/Native project (iOS &amp; Android), and I'm looking for the best way to drop DB (all tables).
  <em>User case: use log out from the app.</em> So, I was looking for a way to erase data from all tables.
  So far I tried this, but I don't have access to <code>sqlite_master</code> table:</p>
  <pre><code>dropAllTables:
    PRAGMA writable_schema = 1;
    DELETE FROM sqlite_master WHERE type IN ('table', 'index', 'trigger');
    PRAGMA writable_schema = 0;
    VACUUM;
    PRAGMA INTEGRITY_CHECK;
  </code></pre>
  <p>Error: <code>No table found with name sqlite_master</code></p>
  <p><strong>What is the best way to drop all table with <code>SQLDeligth</code>?</strong> (I want to avoid writing <code>DROP TABLE</code> fro each table)</p>
  <p>Also, <code>upsert {</code> doesn't seems to work for me as well.. don't know how to provide <code>label</code> for it .</p>
