The JDBC driver does not currently support this behavior and if it did it
would implement it using 2) behind the scenes, so that's a good approach.

Also it's not clear what you mean by a batch, but the use of savepoints
will not allow things like Statement.executeBatch() to commit parts of a
batch. It's all or nothing for these.
