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.
