Yes, because I cannot replicate with just a function:

CREATE OR REPLACE FUNCTION public.search_path_test(integer)
  RETURNS integer
  LANGUAGE plpgsql
AS $function$
BEGIN
     perform * from test_tbl;
     RETURN 1;
END;
$function$

test_(postgres)# \d test_tbl
            Table "test_schema.test_tbl"
  Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
  id     | integer |

pg_dump -d test -U postgres -x -p 5412 -Fc -f dump_search_path.out
pg_restore --single-transaction -d test -c -U postgres -p 5412 
dump_search_path.out

SELECT pg_catalog.set_config('search_path', '', false);

postgres-2019-07-09 10:37:32.488 PDT-604LOG:  statement: CREATE FUNCTION 
public.search_path_test(integer) RETURNS integer
             LANGUAGE plpgsql
             AS $$
         BEGIN
             perform * from test_tbl;
             RETURN 1;
         END;
         $$;



postgres-2019-07-09 10:37:32.489 PDT-604LOG:  statement: ALTER FUNCTION 
public.search_path_test(integer) OWNER TO aklaver;


My guess is the function is being used somewhere.
