this is definitelly not nice approach, but it works.
connect to database, and issue this command:
begin; create table not_previously_existsing(id int4); select xmin from
pg_class where relname = 'not_previously_existsing'; rollback;

returned value is id of the transaction that created the table.
repeat this command every so often (mrtg does that every 5 minutes), and you
can see how it grows.
