Note Submitter: paul at paulmcgarry dot com ---- I do not understand the editors notes in this section. They seem to suggest that you can't safely use nextval to get an identifier from a sequence that will be unique accross all users/sessions. That is categorically false. nextval will pull a number from a sequence and that number is guarunteed to be distinct accross all sessions. To quote the Postgres Docs: "nextval Advance the sequence object to its next value and return that value. This is done atomically: even if multiple sessions execute nextval concurrently, each will safely receive a distinct sequence value."
