I agree we don't want to shorten the window --- I was just pointing out
that we have more upgrade options than in the past. One big push for
shortening was the Win32 issues on 8.0 and perhaps 8.1 that were
unfixable, which helped push retiring, at least on that platforms, and
once you retire on one platform, there is momentum to retire all
platforms for that release.
With Win32 stable on 8.2, we could say we don't need to shorten the
window as much, but pg_upgrade would allow us to keep it the same as now
because upgrades are potentially easier.
