Sorry, this is not the solution for your problem, because this provide
only the actual balance for a single account, but not the history.
Mmh...
A extra table with the oid and the balance for every row in
transactions. Then you can do a index scan, but you need also a trigger
that insert every transaction in this table and calculate the balance.
