Dump and restore problem

Hello, I had a very nice system where I mirrored everything to another
machine each night, so in case of disaster, I could easily switch over
to the mirror.

The backup script uses a line like this:

pg_dump -b -F t -h $postgresql_hostname $i > "$location_backup_dir/`date
+%B-%Y`/$date_info/postgresql_database-$i-backup"

I transfer the backup files by rsync and then run this on the mirror:

pg_restore -c -U dbuser -d dbname -F t postgresql_database-db-backup

This worked fine for months until I upgraded postgres on the main
machine from 8.0.13 to 8.0.15. From then on I started getting these
messages:

pg_restore: [tar archiver] could not open TOC file for input: No such
file or directory

The funny thing is that this started when I upgraded postgres on the
main main machine a little over a week ago, but I had already upgraded
from 8.0.13 to 8.0.15 on the mirror machine back in January (and the
error happens when I try to restore the backup on the mirror).

If anyone can help, I would be very appreciative.
