Isn't that a bit pessimistic?  In tables which mostly grow (as opposed
to deletes and updates) and where most inserts succeed (instead of
rolling back), I would have expected postgresql not to bloat
tables no matter how long my transactions last.

And it's been a while; but I thought transactions like that could
overflow rollback segments in that other database.
