## Description

PostgREST is a standalone server process that automatically transforms a relational database schema into a fully functional RESTful API. By querying system catalogs at startup, it maps tables, views, and stored procedures into standardized web endpoints, allowing developers to build backend services by focusing exclusively on database design.

The service functions as a declarative engine that translates HTTP requests and query parameters directly into native SQL operations. It maintains stateless request processing and integrates connection pooling to manage high-frequency interactions efficiently. Security is enforced by delegating authentication and authorization to the database engine, which maps request tokens to specific database roles and applies row-level security policies to ensure consistent data access.

This approach enables rapid prototyping by eliminating the need for custom application code to handle standard data operations. The system acts as a relational data gateway, ensuring that all interactions adhere to the integrity constraints and permissions defined within the underlying database.
