Buffer replacement in postgresql | Computer Science homework help

 In this project, you will have a chance to study and modify the PostgreSQL source code, with a focus on one of the core modules – the buffer manager. Specifically, you are required to implement the Least Recently Used (LRU) buffer replacement policy by understanding and modifying the current code provided in PostgreSQL, which comes with an implementation of the clock buffer replacement policy. You may find that the amount of code to write in this project is minimal, but you have to understand the codebase first before you know where and how to write your code.
