>From a logical perspective the page is "empty" either way. The only
behavioral difference I can think of is that the initialized page is a
candidate for insertion of new tuples, whereas on the slave it would not
be a candidate until after another VACUUM. So the histories would
diverge faster once the slave comes alive. As long as the slave is just
following WAL records and not making any decisions of its own, I can't
see a failure mode; but it looks like a potential weak spot for future
extensions (particularly, trying to allow slave servers to execute
queries).
