How long companies selling "postgresql support" support each release could be one of the more important characteristics that differentiates one vendor from another. I think it would be useful on postgresql.org's professional support pages to list such policies like "company X supports version 7.2 through 2007; 8.0 through 2009" etc. Do any of the support organizations besides Red Hat specify how long they'll support particular versions? If you're asking about community support I'd hope the answer is "so long as supporting them is a good use of the community's time when compared to other work". Since understanding failure modes over long periods of time is probably of great interest for database developers one could guess that this means old versions will be supported as long as they're pretty similar to the newest version.
