For completeness sake, it should be mentioned that Oracle's way of
dealing with this is no less sensible. Oracle's transactions are
atomic in the sense that all of the statements that did not raise an
error are committed atomically. If any of the statements fail,
it's up to the application programmer to decide whether or not it
makes sense to continue with the remaining statements.
