Row Level Security PostgreSQL — Examples & 2025 Guide

Row Level Security (RLS) in PostgreSQL is a critical feature for enforcing fine-grained access control in your databases. It enables database admins and developers to restrict which rows in a table a particular user, group, or application can access or modify. As data privacy expectations and regulations tighten in 2025, mastering RLS is more important than ever—especially for enterprises managing multi-tenant data, regulated industries, or collaborative apps.

However, writing and managing RLS policies can quickly become complex. That's where AI2sql platform steps in: it takes your requirements in plain English and generates airtight RLS SQL for you: no manual policy tinkering required, instant results, and enterprise-ready security.

Understanding Row Level Security in PostgreSQL

• Purpose: Restrict user access at the row level rather than for the whole table.

• Common Use Cases: Multi-tenant SaaS, HR/payroll systems, medical records, collaborative data platforms.

• Why it matters: Complies with data privacy laws, reduces application complexity, shifts access logic close to the data.

How to Enable Row Level Security in PostgreSQL

1. Enable RLS Feature:

   ALTER TABLE employees ENABLE ROW LEVEL SECURITY;

2. Create a Policy:

   CREATE POLICY employee_isolation_policy
     ON employees
     FOR SELECT
     USING (department_id = current_setting('app.current_department')::integer);

3. Force RLS Policy for All Access:

   ALTER TABLE employees FORCE ROW LEVEL SECURITY;

Real-World Examples of Row Level Security

Below are three practical RLS SQL examples you can generate with AI2sql:

• User-Based Data Isolation:

  CREATE POLICY user_data_policy
    ON orders
    FOR SELECT
    USING (user_id = current_user_id());

• Multi-Tenant Row Filtering:

  CREATE POLICY tenant_isolation_policy
    ON projects
    FOR ALL
    USING (tenant_id = current_setting('app.tenant_id')::uuid);

• Role-Based Record Editing:

  CREATE POLICY manager_update_policy
    ON payroll_records
    FOR UPDATE
    USING (role = 'manager');
