According to many comments, the US government DOES use SQL, and Musk is not understanding much what's going on.
As the user posted, one human can have more than one SSN in their lifetime. Many humans will never have an SSN. Some of those humans may have a TIN. Some humans may have at least one TIN and one SSN at some point.
What are the situations where you can have more than one SSN?
I'm referencing this, but I'm not actually sure: https://www.ssa.gov/OP_Home/handbook/handbook.14/handbook-1401.html
right I did hear the lifelock guy had to get a new SSN, and also Hilda Schrader Whitcher who's SSN was 078-05-1120 and needed to be reissued after her SSN was used as a placeholder in wallets. These seemed to be very uncommon though, and not something I'd expect most systems to be able to handle.
