It doesn't - but those whose work has been committed haven't suffered
due to the process.

Simon wasn't working on replication. He's been doing hot standby which
has been feature-complete (bar the 2PC stuff which I believe Heikki
wanted to hack about in some way) since some time before feature
freeze. At this time it's being reviewed and refactored/debugged as a
result of the feedback he's received which is precisely what feature
freeze is for.

The async replication I believe is not in such good shape, having been
submitted in a working, but primitive form immediately prior to
feature freeze. Although I'd love to see it included in 8.4 (in a form
meeting our normal quality requirements of course), I can appreciate
it should be bumped if it's not practical to bring it up to par in a
reasonable timeframe. I don't believe that decision should be made
until it has had a good first review by a couple of committers who can
assess what might be required. If it's felt it can then be whipped
into shape with a minor delay to the release, then I think it's worth
the wait.
