   <code class="command">ALTER OPERATOR CLASS</code> changes the definition of
   an operator class.
  </p><p>
   You must own the operator class to use <code class="command">ALTER OPERATOR CLASS</code>.
   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 operator class's schema.  (These restrictions enforce that altering the
   owner doesn't do anything you couldn't do by dropping and recreating the
   operator class.  However, a superuser can alter ownership of any operator
   class anyway.)
