Didn't you just ask this question with practically the same wording a
few days ago?

What was wrong with the answers then? What has changed? What's the
*difference* this time?

Repeating your question won't help, you need to ask something more
specific or at least different if you want a useful answer.

If you did not understand the examples you were given last time (which
it sounds like you didn't given your final message) then I strongly
suggest AVOIDING this approach. It is complex, and the solutions
suggested to you require you to understand some PL/PgSQL and a bit about
how locking is used. Are you SURE you can't just use a normal sequence
instead?
