I have an insert using a select of sequences.

insert into ...
    select
        nextval('n') as a,
        currval('n') as b,
        ...
    from lalala
;

Is the order of the target list guaranteed?
That is, will the a and b in the above selection
*always* be the same?

My experiments show this to be true, but I
would like to know that the evaluation of the
target list is never rearranged so that the
values are always predictable.

Thanks,

elein
