The problem on this, from my perspective, is that if you have a transaction
that consists of 20 queries, and the 14th query fails, then you'd like to
be able to abort only the *statement*, recovering in the client application
in whatever way seems appropriate.  Automatically *forcing* a rollback
takes that recovery choice away.
