Comment 21 for bug 1043234

Fixed, I ran the following against the DB to replace the missing constraints.

ALTER TABLE ir_module_module
  ADD CONSTRAINT ir_module_module_category_id_fkey FOREIGN KEY (category_id)
      REFERENCES ir_module_category (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE SET NULL;

ALTER TABLE ir_module_module
  ADD CONSTRAINT ir_module_module_create_uid_fkey FOREIGN KEY (create_uid)
      REFERENCES res_users (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE SET NULL;

ALTER TABLE ir_module_module
  ADD CONSTRAINT ir_module_module_write_uid_fkey FOREIGN KEY (write_uid)
      REFERENCES res_users (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE SET NULL;
