Transfer database from PostgreSQL 12 to PostgreSQL 9.2.24

I need to transfer db from PostgreSQL 12 to PostgreSQL 9.2.24. I try make backup my db from PostgreSQL 12 and restore on PostgreSQL 9.2.24 but I can't do it because have an error like this:

LINE 1: SELECT pg_catalog.setval('public.schemas_headers_types_id_se...
                                 ^


LINE 2:     ADD CONSTRAINT user_id PRIMARY KEY (id) INCLUDE (id);
                                                    ^
Command was: ALTER TABLE ONLY public.users

...

I can't update db version from PostgreSQL 9.2.24 to PostgreSQL 12 because my hosting provider doesn't allow me to do it. How i can't truly transfer my db from PostgreSQL 12 to PostgreSQL 9.2.24?
