I think that's pretty much what he did:

1.) psql dbname
2.) select * from pg_table;

    this lists all th detaild of the tables in the DB.
    some might have owner set to "unknown (sysid=xx)"
    this is the problem. (note the sysid number)

3.) createuser -i xx (sysid user of the unknown table owner)
4.) pg_dump / pg_dumpall

FWIW, I think upgrade is the reason for the pg_dump.
