title: Select Into doesn't work Postgresql
body: <p>I have this two select, the first one worked perfectly. 
  But the second, after ran, does not create the table, but the database has grown.
  So my database grew but I have no table. Where is my table? And why database grew?
  Why the first select worked and the second not? Because have fewer rows?</p>
  
  <p>(Original table cp with 100 million rows)</p>
  
  <pre><code>  (1)
    SELECT * INTO r.cp FROM (SELECT id, mol_from_smiles(canonical_smiles::cstring) m 
    FROM cmps LIMIT 1000) tmp WHERE m IS NOT NULL;
    (2)
    SELECT * INTO r2.cp FROM (SELECT id, mol_from_smiles(canonical_smiles::cstring) m 
    FROM cmps) tmp WHERE m IS NOT NULL;
  </code></pre>
