Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.04

This update uses a new upstream release, which includes additional bug
fixes. Due to upstream security policies, this update removes the ability
of xslt_process() to fetch documents or stylesheets from external URLs.
Please see http://www.postgresql.org/about/news/1407/ for more information.
In general, a standard system update will make all the necessary changes.
