Creating a Read-Only User Account in PostgreSQL
Hello there 👋,
In the world of databases, access control is paramount. It's not always necessary (or safe) to give every user full access to your database. Sometimes, you just need a user who can read data without the ability to modify it. That's where read-only users come in handy.
So, without further ado, let's dive into the steps:
Step 1: Connect to Your PostgreSQL Database #
First things first, you need to connect to your PostgreSQL database. You can do this using the
psql command-line interface or a GUI tool like pgAdmin.
Step 2: Create a New User #
Once connected, you can create a new user with the
CREATE USER command. For example:
CREATE USER my_readonly_user;
Step 3: Grant Connect Privilege #
Next, you need to grant the
CONNECT privilege to the new user for the database:
GRANT CONNECT ON DATABASE my_database TO my_readonly_user;
Step 4: Set User Permissions #
Now, it's time to set the user permissions. You want to grant
USAGE on the schema and
SELECT on all tables in the schema:
GRANT USAGE ON SCHEMA public TO my_readonly_user;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO my_readonly_user;
And voila! You've created a read-only user in PostgreSQL.
Remember, creating a read-only user is a great way to provide data access while maintaining control over your database. It's perfect for users who need to view data but should not be able to modify it.
