I have a rather odd table structure that I would like to simplify to be a view
(for some definition of simplify). The current idea I have is to shovel
values from multiple rows in one table into an array in the view. The tables
look something like this:

create table person (
id serial,
name varchar
);

create table stuff (
person_id references person (id) on delete restrict,
stuff_name varchar
);

The view would go something like:

create view person_with_stuff as
select p.id as id,
p.name as name,
( select s.stuff_name
from stuff
where s.person_id = p.id
)::varchar[] from person p;

Is anything like this possible? I know this may not be good form, but
unfortunately (or perhaps fortunately, since it means I have a job) there are
business reasons for this, supporting old apps and such.

Thanks in advance!
