`NEW' and `OLD' refer to the tuple operated on by this call of the
trigger. They're not valid for FOR EACH STATEMENT triggers, since the
statement might've added/modified/deleted zero or more than one tuple.

If you want to see the values of the tuples modified, use a FOR EACH ROW
trigger.

That's not the case. Your trigger is being called *AFTER* the row is
inserted, so the ID must've been assigned. In any case, default
expressions (including those used to assign values from sequences) are
actually evaluated even before the BEFORE triggers are invoked.
