Comment (by SergeyBiryukov):

 Replying to [ticket:35031 douglsmith]:
 > I have not been able to recreate this condition by adding a new page,
 changing the slug, then adding a new page at the original slug. Those
 older pages had a `_wp_old_slug` custom field set with the original URL
 but that is not being created as I move pages now. So this may only be an
 issue for sites with older page moves.

 `_wp_old_slug` is only added for non-hierarchical post types, see
 [source:tags/4.4/src/wp-includes/post.php?marks=5191-5194#L5185
 wp_check_for_changed_slugs()] and #4328.

 I was able to reproduce the issue with posts:
 1. Set the permalink structure to `/%postname%/`.
 2. Create and publish a new post, "My Test".
 3. Change its slug to `my-test-post`.
 4. Create and publish a new post, "My Test".
 5. The second post redirects to the first one.
