【转载】Postgres创建只读权限的角色

• 创建用户及指定密码：

CREATE USER readonly WITH ENCRYPTED PASSWORD 'Test@1234';

• 设置用户默认事务只读：

alter user readonly set default_transaction_read_only=on;

• 赋予用户权限，查看public模式下所有表：

GRANT USAGE ON SCHEMA public to readonly;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO readonly;

• 赋予用户连接数据库权限：

GRANT CONNECT ON DATABASE demo to readonly;

• 切换到指定数据库：

\c demo

• 赋予用户表、序列查看权限（如果后续有新增的表或者序列则需要再次执行下面指令）：

GRANT USAGE ON SCHEMA public to readonly;
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO readonly;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonly;
