I noticed that "array()" is used in the query that implements the "\du" psql meta-command. It has some similarity with "array_agg()" thus:

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.

https://www.postgresql.org/docs/current/sql-expressions.html

Which on can find fairly directly via the index entry for array:


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