This blog post provides an easy method to implement row-level security in a Postgres database using AWS Cognito for authorization. The process involves configuring AWS Cognito, setting up the Postgres database with Neon and enabling row-level security (RLS), integrating AWS Cognito and the Postgres database using Neon Authorize, testing the application, and verifying RLS policies. The guide uses an app with Neon as the Postgres provider, Neon Authorize, Express.js, and HTMX.
