I would really like to contribute to Postgres, If I can. Please let me
know your thoughts or plans regarding UUID generation.
How is it implemented? I can personally see two ways of generating
sequential UUID:s. Either you use something like PostgreSQL's sequences
or you can implement something based on the system time plus some few
random bits which means they will be mostly sequential.
It could be worth checking on the hackers mailing list if there is any
interest in this feature, but if it works like a sequence it should also
probably be a sequence if it is ever going to be accepted into the core.
For your own use I recommend doing like Merlin suggested and write an
extension. As long as you know a bit of C they are easy to write.
