The only conceivable implementation is an implicit savepoint issued
before each statement.  By and large that seems to me to be most easily
handled on the client side, and many of our client libraries already
have the ability to do it.  (For instance, psql has ON_ERROR_ROLLBACK.)
If we tried to do it on the server side, we would break any client
software that wasn't prepared for the change of behavior --- see the 7.3
autocommit fiasco for an example.

So as far as the server is concerned, I see no TODO here.
