Well, it won't generate any logs for the tuples that were just frozen,
but it will generate logs for tuples that weren't frozen.  How many of
these there are, depends on how many tuples you inserted after the batch
that was just frozen.

If you want to freeze the whole table completely, you can you VACUUM
FREEZE.
