Implement Authorization using Row Level Security (RLS) with Supabase (Step By Step Guide)

From the video description

In this video, Jon Meyers explains how Row Level Security (RLS) works, why you should enable it and how to enable RLS / Row Level Policies in Supabase. Jon steps through implementing some common policies using the Supabase Dashboard and demonstrates how rules across multiple tables can work together to restrict access. PostgreSQL provides a simple syntax for RLS, allowing access rules to be declared in the Database itself. This can make queries more efficient as the client can query the Database directly, without the need for a middleware API.
