The UUID spec update has not been finalized yet.

It would be quite unfortunate to end up with a UUID v7 in PostgreSQL that’s not quite the standardized one because the patch got merged too quickly.

EDIT: here is the IETF working group page https://datatracker.ietf.org/wg/uuidrev/about/

Their milestone seems to submit the final proposal by March.

The chances of that seem extremely low at this point. The contents of a version 7 UUID have not changed since work started on RFC 4122 bis in October 2022: https://author-tools.ietf.org/iddiff?url1=draft-ietf-uuidrev...

The chances may be low, but either it's a draft or a final version.

There's clearly little pressure to rush this, considering it's not difficult to add a custom function generating UUIDv7 ...
