Not quite right. SETOF returns many items so you could have:
create function list_ids() returns setof int4 as 'select id from foo;'
language 'sql';
select list_ids();
list_id

1
2
7
12
You can also return a tuple like:
create function whole_row() returns foo as ...
But - that can only be used to feed into another function, not in a
"raw" select statement.
