Are you really doing half a billion transactions a day? Keep an eye on
age(pg_class.datfrozenxid) as suggested in the manual to see what's
going on.
It's hard to credit getting any useful work done at the rate of 10K
transactions per second, but if you have a client that is issuing a
constant stream of dummy operations (like begin/rollback) it's
conceivable that you could advance the transaction counter that fast.
