      <para>       Support for abbreviated keys has also been added to the non-default       operator classes
<literal>text_pattern_ops</>,      <literal>varchar_pattern_ops</>, and <literal>bpchar_pattern_ops</>.
Processingof ordered-set aggregates can also now exploit       abbreviated keys.      </para>     </listitem>
 

Is it really sensible to group f1f5ec1ef together with the others?  I
think that one should be its own entry.
