row-level-security

Row-level security in PostgreSQL restricts data access by evaluating policies against tenant IDs, ensuring users only see their own records. This Skill helps design and implement fine-grained RLS policies to enforce strict tenant isolation and role-based access control for SaaS architectures.

Yes, Supabase supports row-level security policies for attribute-based access control. This Skill helps you create fine-grained access policies directly within Supabase to manage team and organization sharing while securing data at the database level.

Row-level security performance bottlenecks often occur when policies force complex per-row evaluations. This Skill helps debug and optimize RLS policies by troubleshooting access issues and refining policy logic to reduce query overhead in PostgreSQL and SQL Server.

This row-level security Skill supports SQL Server, PostgreSQL, and Supabase. It helps you implement, debug, and optimize access control policies across all three platforms to ensure users only access authorized database records.

Troubleshooting database RLS policies involves reviewing policy definitions and checking role configurations to identify why users cannot see their data. This Skill debugs common row-level security access issues to ensure policies return the correct authorized records.

You should avoid row-level security when policy evaluations create severe performance bottlenecks that cannot be optimized, or when your application architecture requires access control logic outside the database. This Skill helps assess and optimize RLS policies to mitigate known limitations.
