pg_listener table in catalogs.sgml

Hello,

I noticed that there is column number mismatch in document of system
catalogs, pg_listener(catalogs.sgml, http://www.postgresql.org/docs/8.4/static/catalog-pg-listener.html).

I think it shuld be:
$ diff catalogs.sgml catalogs.sgml-honda
3033c3033
<    <tgroup cols="4">
---
>    <tgroup cols="3">
3038d3037
<       <entry>References</entry>

regards,
