What problem does it solve?

This Skill addresses the gap in static analysis by providing a framework for dynamically testing PostgreSQL schemas, ensuring runtime behavior aligns with design, especially for critical aspects like Row-Level Security (RLS), trigger logic, and constraint enforcement.

Core Features & Use Cases

• RLS Policy Validation: Design and review tests to prove tenant isolation and access control.
• Trigger & Constraint Testing: Verify side-effects of triggers and the enforcement of constraints.
• Performance Regression Detection: Use EXPLAIN cost tracking and RegreSQL for query plan baselines.
• Use Case: When implementing a new RLS policy, use this Skill to write pgTAP tests that simulate different user roles and tenant contexts to confirm that only authorized data is accessible.

Quick Start

Write pgTAP tests to verify RLS policies for tenant isolation.
