title: how to rename a table without re creating it
body: <p>I didn't find a RENAME option to alter table name.
  I have a case that I must rename a table, and the only way is to select with result to new table. this query cost money, and taking long time for no reason.</p>
  
  <p>It is especially painful when I need to rename a nested table, so I must export, need to even work on the result set in order to import it back.</p>
  
  <p>Any way that I am missing? anything coming soon? </p>
