This tutorial explores the use of Postgres's memory management system, specifically **MemoryContext**s, by building a simple HTTP server within a Postgres extension. The project demonstrates how to allocate and manage memory efficiently using Postgres's built-in memory context infrastructure, which simplifies memory management by automatically freeing allocated memory when the context is reset.
