There is no SKYLINE command in any version of Postgres.
A couple of different people have shown work-in-progress patches that
add a function by that name, but those haven't gotten to the point of
being serious submissions and very likely wouldn't have been accepted
if they were. I'm not even sure that those did what you want anyway,
since there's no standard for such a feature.
