Обсуждение: variadic function, query "in", help with syntax/function

Briefly, what would it take to make the following work?

create function getbatch (variadic ids int8[]) returns setof foobar as $$
begin
    return query
        select * from foobar where id in (ids);
end;
$$ language plpgsql;

create function getbatch (variadic ids int8[]) returns setof foobar as $$
begin
        return query
                select * from foobar where id = any (ids);
end;
$$ language plpgsql;

note, for these single statement function, sql language is better

Ah, thanks, I didn't know any worked in that context--I've just used it (and only seen examples) the other way:
const_id= any(somecol).

I greatly simplified it for the question; it's kind of a nasty function that's multiple unions of multiple joins.
