为远程连接设置PostgreSQL特权

Question

I want to set a user which I can use remote, that for a database can:

• do any rows operations
• can't add new columns
• can't delete/create database or tables
• I don't want the user to have access to other databases

I executed:

GRANT ALL PRIVILEGES ON DATABASE "example" to user_name;
REVOKE CREATE ON DATABASE "example" FROM user_name;

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO user_name;

The following fails:

REVOKE CREATE ALL TABLES IN SCHEMA public FROM user_name;

    invalid privilege type CREATE for relation

Can you, please, add all necessary steps.

Answer 1

You probably want to keep the user from crating tables in schema public .

For that, you must revoke the CREATE privilege on that schema which is by default granted to everybody:

REVOKE CREATE ON SCHEMA public FROM PUBLIC;

If you want to user to have permissions on tables that will be created in the future, consider using ALTER DEFAULT PRIVILEGES .
