When I try to insert a duplicate row, this generates an IntegrityError
on my unique index, which rolls back my entire transaction, when I
really want it to generate a ROLLBACK TO SAVEPOINT for the most recent
savepoint, so only that insert is ignored.  Does anyone know a
configuration trick to get it to do this, or do I have to write a
stored procedure where I explicitly call ROLLBACK TO SAVEPOINT?
