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.
