If there is a natural sequence (e.g. - a value assigned by nextval()),
that offers a natural place to apply the usual order-imposing ORDER BY

Note: "INSERT … RETURNING" doesn't accept an ORDER BY clause.
No, but you can wrap the INSERT .. RETURNING in a CTE and order that.
Personally I find that a not very practical suggestion. It means you need the
ability to sort the data equivalently on the clientside which isn't always
easy if you consider platform/locale and whatever differences.
Er, what?
with orig_inserts as
(
insert into table_1
...
returning *
),
ordered_inserts as
(
select * from orig_inserts
order by ...
)
insert into table_2
select * from ordered_inserts ...;
why does the client have to be involved, exactly?
