Describe Miniconfs/PostgreSQL/HackersGuide here.
In the Introduction to the PostgreSQL internals session, attendees will learn about the PostgreSQL development process and coding conventions. Key aspects of the database backend will be surveyed at the code level. Finally, a non-trivial patch will be examined. The patch will touch interesting parts of the parser, command processor and executor. This talk is the most detailed introduction to the PostgreSQL backend available.
When finished, you'll be ready to work on your own contribution to PostgreSQL.
The talk is designed for people familiar with programming (in C).
