   <code class="command">ALTER STATISTICS</code> changes the parameters of an existing
   extended statistics object.  Any parameters not specifically set in the
   <code class="command">ALTER STATISTICS</code> command retain their prior settings.
  </p><p>
   You must own the statistics object to use <code class="command">ALTER STATISTICS</code>.
   To change a statistics object's schema, you must also
   have <code class="literal">CREATE</code> privilege on the new schema.
   To alter the owner, you must also be a direct or indirect member of the new
   owning role, and that role must have <code class="literal">CREATE</code> privilege on
   the statistics object's schema.  (These restrictions enforce that altering
   the owner doesn't do anything you couldn't do by dropping and recreating
   the statistics object.  However, a superuser can alter ownership of any
   statistics object anyway.)
