It doesn't matter how exceptional Java's exception handling is.
PostgreSQL's exception handling is just like a black hole - once the
gravity got it, you won't get your transaction back ever.
The current effort on subtransactions might change that. But I'm not
sure what performance impact or other side effects it will have to
execute every single statement inside of a stored procedure as a
separate subtransaction just to have catchable exceptions.
