You could show the current transaction Id, which is also useful.
(Presently there's no way to know even a backend's own TransactionId,
and people is suggested to use hacks like insert a row in a table and
check its xmin.)
Maybe we could add an adittional view, with all the info from ProcArray,
which is useful sometimes. Then you could join that to pg_locks, and it
would work even if the statistic collector is disabled.
