          @imor Please verify this is not my setup and help to get rid of the error:

begin;

create schema if not exists a1; grant usage on schema a1 to public;
create table a1.foo(id int primary key); grant select on table a1.foo to public;
insert into a1.foo (id) values (1);
create or replace function a1.bar(a1.foo) returns int[] stable return array[1, 2, 3]::int[];
grant execute on function a1.bar(a1.foo) to public;
set local search_path to a1;
comment on schema a1 is e'@graphql({"inflect_names": true})';
select graphql.resolve($$query {fooCollection {edges{node{ id bar }}}}$$); -- invalid return type from function

rollback;
