You said data import, so I assumed it was pulling rows into an empty table. The example I posted was a way to create a table with a static integer PK that you could rapidly generate in a loop, and then later convert it to auto-incrementing.

IME, if something is easy with RDBMS in prod, it usually means you’re paying for it later. This is definitely the case with UUIDv4 PKs.
No I mean an active prod table with people adding new rows all the time. It's just so much easier not having to worry about integer conflicts and auto-incrementing shenanigans.
But I get you like integers so whatever works for you, I just don't think they're the right tradeoff for most projects.
