By the way, the Go language has also already implemented a function for UUIDv7: https://pkg.go.dev/github.com/gofrs/uuid#NewV7

That's right! There is no point in waiting for the official approval of the new RFC, which obviously will not change anything. I have been a contributor to this RFC for several years, and I can testify that every aspect imaginable has been thoroughly researched and agreed upon. Nothing new will definitely appear in the new RFC.

Here's v12. Changes:
1. Documentation improvements
2. Code comments
3. Better commit message and reviews list
Thank you, Andrey! I have just checked v12 – cleanly applied to HEAD, and functions work well. I especially like that fact that we keep uuid_extract_time(..) here – this is a great thing to have for time-based partitioning, and in many cases we will be able to decide not to have a creation column timestamp (e.g., "created_at") at all, saving 8 bytes.
The docs and comments look great too.
Overall, the patch looks mature enough. It would be great to have it in pg17. Yes, the RFC is not fully finalized yet, but it's very close. And many libraries are already including implementation of UUIDv7 – here are some examples:
- https://www.npmjs.com/package/uuidv7
- https://crates.io/crates/uuidv7
- https://github.com/google/uuid/pull/139
