Below are the unique age(relfrozenxid) values that i see from the above query

# psql -U postgres -d dbname -c "select relname, age(relfrozenxid) from pg_class
where relkind in ( 'r', 't') order by 2 desc;" | awk '{print $3}' | sort | uniq

140835139
150945753
185741480

They are all under 200 million - Also please refer to
http://archives.postgresql.org/pgsql-general/2008-07/msg00195.php. I have
provided more details in here.
