Hello pgsql-hackers! As you may know there's a new version of UUID being standardized [0]. These new algorithms of UUID generation are very promising for database performance. It keeps data locality for time-ordered values. >From my POV v7 is especially needed for users. Current standard status is "draft". And I'm not sure it will be accepted before our feature freeze for PG16. Maybe we could provide a draft implementation in 16 and adjust it to the accepted version if the standard is changed? PFA patch with implementation.
What do you think? cc Brad Peabody and Kyzer R. Davis, authors of the standard cc Kirk Wolak and Nik Samokhvalov who requested the feature Thanks! Best regards, Andrey Borodin. [0] https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04
