  12    <code class="command">ALTER OPERATOR CLASS</code> changes the definition of
  13    an operator class.
  14   </p><p>
  15    You must own the operator class to use <code class="command">ALTER OPERATOR CLASS</code>.
  16    To alter the owner, you must be able to <code class="literal">SET ROLE</code> to the
  17    new owning role, and that role must have <code class="literal">CREATE</code>
  18    privilege on the operator class's schema.
  19    (These restrictions enforce that altering the
  20    owner doesn't do anything you couldn't do by dropping and recreating the
  21    operator class.  However, a superuser can alter ownership of any operator
  22    class anyway.)
