Right offhand I do not see how a failed transaction could make any
entries (that later xacts could see, that is) in such a table. And
surely error entries are precisely the most interesting ones in a log.
So you'd need to commit some major-league abuse of the transactional
and MVCC mechanisms to make this work usefully.
