I updated the page already to be clear about what versions of PostgreSQL
it works on, and it directs people to Shaun's original message if they
are running 8.2. The only people who might get confused now are the
ones running EDB's versions, where the exact features you get in
particular versions can be slightly different than the community
version. But that problem both exists in other parts of the wiki, and
is a bit outside of its scope to try and address.
