Yes, I was actually just about to post a follow-up to my previous message
because I just found out that pgsql doesn't support this.

Yes, I just found that out too.

But given that pgsql doesn't allow me to immediately retrieve the value of
the autogenerated key, how can I (or can't I!?)? If I made a

SELECT MAX(id)

statement right afterwards then I couldn't be sure that that is the id just
generated, because due to concurrency someone else may have just submitted
an entry too, right?

How are these things done in pgsql?
