Yes, if you want to support new records being added it's up to you to include something like a created date as part of your specified sort order.

More than page_size records with that value works fine - that's why the primary key is included as a tie-breaker.

Doesn’t that take you back to the original problem though: if you delete the primary key the query fails?

Would the created_at be a better option than the primary key? That can’t be deleted or changed, and that would give you a stable secondary sort?
