You probably filled the test table and then vacuumed within a single
checkpoint cycle, so that the replay sequence included loading data into
page 1 in the first place. The risk case is fill table, checkpoint,
vacuum, crash; because then the replay starts from the checkpoint and
won't re-create page 1.
