It seams the inserts can't be chained? :(
The inner insert works when I run it separately but when I run the
chained inserts I get an syntax error.
How can a script use what RETURNING dumps out?
I tried a bit but got nowhere.

insert into staff_2_project ( staff_fk, project_fk )
insert into staff ( company_fk, ..., department_fk )
[...]
returning staff_id, 42 as project_fk;

and

insert into staff_2_project ( staff_fk, project_fk )
(
insert into staff ( company_fk, ..., department_fk )
[...]
returning staff_id, 42 as project_fk
) as s;

and

insert into staff_2_project ( staff_fk, project_fk )
select staff_id, project_fk from
(
insert into staff ( company_fk, ..., department_fk )
[...]
returning staff_id, 42 as project_fk
) as s;
