That's what I'm guessing too; see the previous report here:
http://archives.postgresql.org/pgsql-admin/2007-12/msg00254.phphttp://archives.postgresql.org/pgsql-admin/2008-01/msg00023.php
The symptoms are a bit different (eg, large value instead of zero
for MAXALIGN) but that's not too surprising considering that 8.1
and 8.2 have different sets of fields in pg_control.
You'll need to get binaries that matched your originals and then
reinstall the database from your backup.
