OK, got it, so if someone makes a session change while in a transaction,
and the transaction aborts, should the SET be rolled back too? If not,
then we should honor the SET's that happen after the transaction aborts.
However, Tom's schema changes require a db connection, so it is hard to
honor the SET's once the transaction aborts. That is how we got to the
abort all SET's in an aborted transaction.
