I realize that this is a feature and not a bug, but what I ran into confronting the same issue was the fact that the servers listen on different ports and when I uninstalled the older version, the newer version was listening on a non-standard port. This caused some confusion for awhile.
I also realize that having both versions on the same port may be both impossible and unwise or some power of both, but is there a standard port that they are "competing" for in some dark server hell.

The one-click installers are designed in such a way that you can have different major versions of postgresql co-exist on the same machine. Thats the reason, the 8.4.1 installer doesn't realize that 8.3 is even installed.

Hi,
We have tried this at least with Windows 2008 64-bit server and the problem
is very reproducible (multiple systems):
1. Install 8.3 on some non-C drive (say E:\)
2. Run the 8.4.1 installer to upgrade this install
it appears that the 8.4.1 doesn't realize 8.3 is even installed
Result: Installation fails with a permission problem. It seems certain files
from 8.3 are not able to be deleted. When I manually try to delete them,
even with the Administrator user, it fails. I ultimately needed to take
ownership and then give Full Control before I was allowed to delete them.
There is no problem with this upgrade on the C:\ drive.
Thanks
