As I understand you want to be able to see record versions. Do you intend to
see all of them? I think this only can have benefits in conjuction with
transactions IDs and user or connection data for these transactions. And for sure
such uncommited transactions must be read-only for every user but the most expert.

And what about the triggers, which are not in transaction content? Such a
trigger can log all the database activity, not only commited.
