The postgis mailing lists could probably offer you better advice about
exactly how to update a postgis installation, but my uninformed guess
would be that you have to load 8.2 postgis into the (empty) target
database before you restore. This defeats the dump script's attempts
to install 8.1 postgis objects, which aren't compatible.
