Adding an table of contents in SGML

I would like to add a table of contents to the top of the 8.4 release
notes:

	http://developer.postgresql.org/pgdocs/postgres/release-8-4.html

Similar to the one at the top here:

	http://developer.postgresql.org/pgdocs/postgres/datatype.html

I tried poking around but didn't find any obvious way to do it.
