When this happened, did you get anything in the eventlog? Or in the

These errors indicates a proper install where the server crashes after
install, and not a problem with the installer specifically.

Did you install it into the default directory, or a different one? Was
this directory completely empty when you started?
(This goes for both the base dir of the install and the data directory)

Uh, what upgrade script is that? There is no upgrade script from 8.0.4
to 8.1.0.
The proper upgrade path is:
1) pg_dump your old version
2) (optionally) uninstall the old version. At least stop it, or place
the two versions listening on different TCP ports.
3) Install the new vgersion
4) reload your dump from step 1 into the new version
Did you perform all these steps in order?
