We plan to upgrade to version 9.1, do you know if file result of the

Yes, pg_dump output from 8.3 should restore fine to 9.1. PLEASE READ THE
RELEASE NOTES for the intermediate major versions (8.4 and 9.0) for
upgrade advice and caveats.

Do not just try to upgrade your production database. Do a test with a
test copy first, and test your application against it; don't just assume
it'll all work.
