Youcan do so without damaging the transaction by creating a savepoint immediately beforehand, but this will cause you
tolose the state of the named savepoint. Example below.

Thanks. That's interesting, protecting a questionable
release with another savepoint. I wouldn't have thought
of that. But I'm not sure it helps my ultimate goal of
simplifying my application code or that it doesn't shift
the problem of not leaking savepoints to the test
savepoints.
