The only thing I can come up with is to eliminate the FK :
 fk_code integer not null
               references code_root(pk_code_root)
               on update restrict
               on delete restrict
on lnk_codes2epi and replace it with a trigger that essentially does the same 
thing ; check for presence of pk_code_root.
