How to use update as a inner subquery in postgresql?

update unit_has_jobcard 
    set status = 'approval' 
where id = (update jobcard_has_approvals 
                      set approve = true 
            where id = 27 
            returning id);

You need a common table expression to update two tables in a single statement:

with approvals as (
  update jobcard_has_approvals 
     set approve = true 
  where id = 27 
  returning id  
)
update unit_has_jobcard
  set status = 'approval' 
where id = (select id from approvals);
