PostgreSQL - Roles and Security

You wrote this policy:

CREATE POLICY access_policy ON projects FOR SELECT USING (user_id = current_user);

But queries still return all rows to all users. What is the likely mistake?

ARow-level security is not enabled on the projects table.

BThe policy syntax is incorrect and causes an error.

CThe policy should use session_user instead of current_user.

DThe policy needs a TO clause specifying users.

Step-by-Step Solution

Solution:

Step 1: Check if RLS is enabled
Policies have no effect unless RLS is enabled on the table.
Step 2: Identify why all rows are visible
If RLS is off, all rows are visible regardless of policies.
Final Answer:
Row-level security is not enabled on the projects table. -> Option A
Quick Check:
RLS must be enabled for policies to apply = Row-level security is not enabled on the projects table. [OK]

Quick Trick: Enable RLS before creating policies to enforce row filtering. [OK]
