Your patch looks good to me.

I didn't mean that adding more information about the "uuid" data type is
a bad thing.  Perhaps that additional paragraph could be

    RFC 9562 defines 8 different UUID versions.  Each version has specific requirements
    for generating new UUID values, and each version provides distinct benefits and drawbacks.
    <productname>PostgreSQL</productname> provides native support for generating UUIDs
    using the UUIDv4 and UUIDv7 algorithms.  Alternatively, UUID values can be generated
    outside of the database using any algorithm.  The data type <type>uuid</type> can be used
    to store any UUID, regardless of the origin and the UUID version.

I would be happy if you added something like that again.
