> Using a random UUID as primary key does not mean users have to memorize that UUID. In fact in most cases I don't think there's much reason for it to even be exposed to the user at all.
So what is such an identifier for? Is it only for some technical purposes (like replication etc.)?
Why bother with UUID at all then for internal identifiers? Sequence number should be enough.
