Postgresql 只读角色和用户

Question

我找不到这个问题的答案：为什么在授予权限后从表中选择会失败？

-- create new role
CREATE ROLE readonly;

-- grant access to all existing tables
GRANT CONNECT ON DATABASE shop TO readonly;
GRANT USAGE ON SCHEMA public TO readonly;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonly;
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO readonly;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO readonly;

-- grant access to all table which will be created in the future
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO readonly;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON SEQUENCES TO readonly;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT EXECUTE ON FUNCTIONS TO readonly;

-- create user and grant role to this user
CREATE USER b_readonly WITH PASSWORD 'reAdOnLy123';
GRANT readonly TO b_readonly;

我来自 db 的错误消息如下：

错误：关系 customer_search_query SQL 状态的权限被拒绝：42501

Postgresql 9.6.5 中是否有一些新技巧？

Answer 1

您查询的表很可能customer_search_query不在公共模式中。尝试运行此命令。

GRANT SELECT ON customer_search_query TO readonly;
