In the general case I think plenty of people update and build from CVS
regularly. It's great that the FSM has been in for a couple months
before the beta, we've uncovered a couple problems which could easily
have slipped through the betas for example.

In the case of hot standby and replication I'm not really sure that
logic applies. It takes quite a lot of work to test these features and
they don't turn up problems in other areas when you're not running
them. So I doubt it would really have helped in this case.
