In my opinion you should look at 8.2, not 8.1. And 8.3 is on the
horizon :)

Be sure to use the 8.2 pg_dump, not the 7.1 pg_dump, against the 7.1
database.

It would be helpful if you provided the exact pg_restore command
you're using (again, it should be the 8.2 version of pg_restore) and
the exact error you're getting. Otherwise it's difficult for us to
know what's going on.

You might need to use adddepend, which is a contrib module included
in 8.1 (not 8.2 AIUI). (Perhaps 8.2 includes this functionality in
core? You can probably check the release notes for 8.2 for details.)

Not only the hardware :) 7.1 includes known data-eating bugs.
