My question would be why are you using age() on relfrozenxid?
From here:
http://www.postgresql.org/docs/8.3/static/catalog-pg-class.html
relfrozenxid xid All transaction IDs before this one have been
replaced with a permanent ("frozen") transaction ID in this table. This
is used to track whether the table needs to be vacuumed in order to
prevent transaction ID wraparound or to allow pg_clog to be shrunk. Zero
(InvalidTransactionId) if the relation is not a table
From here:
http://www.postgresql.org/docs/8.3/static/functions-datetime.html
age(timestamp) interval Subtract from current_date
So it is not surprising that it is not working.
