On 8.2 you could have the problem that leftover temp tables are messing
up the frozenxid calculations, but I don't think that can happen on 8.1
Can you verify whether age(pg_database.datfrozenxid) is shrinking after
vacuuming? If the age() of a database is higher than the applicable
max_freeze_age, then it will always be chosen.
