PostgreSQL is a globally renowned open-source database, widely utilized across various industries. It was honored as the DBMS of the Year in 2023 by DB-Engines Ranking[1]. One of the key factors contributing to its popularity is its extensibility. Extensions allow users to add new features to PostgreSQL. Despite many users' desire to create extensions, a clear guide on where to start has been lacking. Last year, I gave a talk on taking the first steps towards developing extensions[2]. This year, I will present a more advanced lecture. Initially, I will explain how to develop a simple extension, followed by a detailed exploration of my developed extensions that provide features like "Automatic Query Execution Plan Tuning" and "Automatic Hint Clause Generation" through the extension pg_plan_advsr[3]. I will explain the hooks used, the mechanisms involved, their impacts, and provide demonstrations. The intended audience includes individuals interested in PostgreSQL, those eager to develop extensions, and anyone keen on query performance enhancement. My hope is that this talk will contribute to the growth of the PostgreSQL community.

This talk includes the following contents:
- Explanation of PostgreSQL
- Overview of extensions
- Introduction of a simple extension example
- Explanation of the mechanism and the merits of my extension pg_plan_advsr
The intended audience includes individuals interested in PostgreSQL, those eager to develop extensions, and anyone keen on query performance enhancement. I hope this talk will contribute to the growth of the PostgreSQL community.
