postgres新架构以继承用户的权限

CREATE ROLE read_only WITH LOGIN PASSWORD 'password' 
NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE NOREPLICATION VALID UNTIL 
'infinity';

然后我给了你选择的许可

GRANT USAGE ON SCHEMA public TO read_only;
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO read_only;
GRANT SELECT ON ALL TABLES IN SCHEMA public to read_only;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO 
read_only;

我的要求是,只要添加了新架构,它就应该继承只读用户的权限。目前,我手动为新架构分配这些权限。
