try something like
CREATE FUNCTION execute(in_sql TEXT) RETURNS void as $$
BEGIN
EXECUTE in_sql;
RETURN;
END;
$BODY$ language plpgsql;
select execute(
$$select setval( '$$
|| table_name ||
$$_id_seq', coalesce((select max(id) from $$
|| table_name ||
$$),1), false ) $$
) from information_schema.tables where you want;
