+   <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 be able to <code class="literal">SET ROLE</code> to 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.)
