Quick guess: Put single quotes around the name of the sequence
create table test.my_table_2 (
id bigint not null default public.nextval ('test.my_sequence_id'),
type test.my_type not null,
length bigint,
primary key ( id )
);
Otherwise it tries to evaluate "test.my_sequence_id" as if it were a
scalar subquery, which does not have a FROM clause, so fails.
