PostgreSQL - Roles and Security

You wrote this policy to allow users to update their own rows:

CREATE POLICY update_own ON orders
FOR UPDATE USING (user_id = current_user);

But users report they can update other users' rows too. What is the likely problem?

AThe policy should use WITH CHECK instead of USING

BThe policy must be created with FOR SELECT, not FOR UPDATE

CThe current_user function is not supported in policies

DRow-level security is not enabled on the orders table

Step-by-Step Solution

Solution:

Step 1: Check if RLS is enabled
Policies only work if row-level security is enabled on the table; otherwise, they have no effect.
Step 2: Understand the symptom
If users can update rows despite the policy, likely RLS is disabled, ignoring policies and allowing full access.
Final Answer:
Row-level security is not enabled on the orders table -> Option D
Quick Check:
RLS must be enabled for policies to work [OK]

Quick Trick: Enable RLS to enforce policies [OK]
