create temporary view x(v) as (values (17), (42));
select array_agg(v) from x;
select array(select v from x);Anyway, I can't find where "array()" is documented. Google does find me a hit on stackexchange.com <http://stackexchange.com>. But it doesn't x-ref to the PG doc.

Or browsing the syntax chapter via the table of contents (everything is either a function or syntax, and you ruled out the former).
