Thanks David, I agreed.
Also 6bdf1303 should be included like below,

<!--
 Branch: master [6bdf1303b] Avoid wrong results for power() with NaN
+Branch: master [61b200e2f] Avoid wrong results for power() with NaN
 -->
 
        <para>
         Consistently return <literal>NaN</literal> for
         <literal>NaN</literal> inputs to <function>power()</function>
-        on older platforms (Dang Minh Huong)
+        on older platforms (Tom Lane, Dang Minh Huong)
        </para>


Thanks and best regards,
