A sequence to hold the id was defined with:

MAXVALUE 9223372036854775807 START 101
CACHE 1;
The function wich allocates the id and defines the datum is:
CREATE FUNCTION test_verif() RETURNS trigger AS $test_verif$
BEGIN
select into NEW.id nextval('test_azon_seq');
NEW.datum := current_timestamp;
RETURN NEW;
END;
$test_verif$ LANGUAGE plpgsql;
I take it this is just an example, because you could do this with
DEFAULTs on both columns.
When I issue an insert (see below) how can I retrieve the
inserted value of id? I need something like Oracle's returns
for insert.
insert into "public"."test" (nev) values ('text');
SELECT currval('public.test_azon_seq');
And yes, it will cope with multiple concurrent connections inserting.
