M$ is about to end the last remaining bit of support for it, and has already stopped publishing non-security fixes. It looks like there are lots of legacy installations still out there (heck, I see lots of RH7.3 and it's also out of support). But there isn't any legacy native W32 Postgres, so we would not be affecting any legacy users by not supporting NT4. Thoughts? cheers andrew

But I became a bit uncertain when I recently saw the support request from an Indian user who wanted to run on win98, which is certainly even harder than NT. I wonder how many people would not have the chance to try pgsql because they can't afford a system that's sufficiently up to date. We have limited resources, so we'll have to concentrate on main stream; older platforms shouldn't restrict the functionality of the standard installer. OTOH, if somebody has the time to create support documents so non-supported win32 platforms can be used too, this would be probably appreciated. My .02 social cents. Regards, Andreas

I think Dave and Merlin have just showed us that, in addition to the eventlog limitations, there are enough other reasons to say we really can't. As for Andreas' point about people wanting to try PostgreSQL out on low-cost platforms, if they need Windows they can use Cygwin still, and otherwise they can use Linux or FreeBSD. The point is that we have limited resources, and should not strain them trying to support a platform that is itself unsupported and that makes life difficult/impossible for us. If we had legacy users it might be a different story. cheers andrew
