Not conveniently in V1.x, but V2 includes a new feature - an extension
to the insert verb that returns values from the inserted row. The
syntax will be something like this:

INSERT INTO <table> (<field list>) VALUES (<value list>) RETURNING
(<field list>)

As you noticed, this doesn't work in the multi-user case.

That's expensive unless you have a descending index, and unreliable for
read committed transactions.
