This guy sounds like he has bad backups and bad database management. Nothing more. That "database ID" is probably an auto-incrementing primary key, and yes, moving it to another box, restoring from backups, and even migration to another server type should keep the same ID. If not, you've done it wrong. In none of those situations will new entries necessarily follow the same pattern, i.e. there may be huge gaps or it might start filling in deleted questions so entries are "out of order", but those are separate problems and also remedied by using your schema correctly. In short: this post is very misinformed and I hope that it's presented for that purpose and not taken as serious advice.
