I think you're looking for the GROUPING() function. See
http://www.postgresql.org/docs/9.5/static/functions-aggregate.html
It just dawned on me that you may note have meant having them in a
specific sequence in the result set. Even still, I think it's much more
clear being explicit with what rows are included and which aren't.

Why? You're already provided with this information: NULL fields are not
being used in the grouping set for the row. Moreover, it would seem to
be an implementation- and run-time- dependent value, as there is no
reason group by grouping set (a,b), (c,d) couldn't be executed in
written order, or
It would help if the resultset has some param to mark which is which with
the grouping sets index.
for example, the results for (a,b,c,d) would be marked as for index =0,
(b,c,d) would be index=1

Do you want to know if a row is from the (a,b) or (c,d) group? All rows
will contain (a,b,c,d) but (a,b) will be NULL for the (c,d) grouping
sets, and vice-versa.
