pg_restore question

We're backing up our database using pg_dump with compression.  We're
selecting each database however when we tried running a pg_restore
everything cept for the roles were restored.

I'm digging through the pg_restore options, Is there an option I'm
forgetting to include?

Also we're restoring from an 8.3.8 database to a 9.0 database.  Not sure
if that's part of our problem.

Digging through the docs we're doing 'pg_restore -C -d postgres data.dmp'

Am I missing something?

Thanks!
