Introduction to PostgreSQL

🐘COURSE OVERVIEW

This is an exhaustive, architecturally-focused guide to PostgreSQL. You won't just learn to write SELECT statements; you will learn how the engine handles memory, how B-Tree indexes work under the hood, how to analyze query plans with EXPLAIN ANALYZE, and how to scale to millions of users using replication and connection pooling. We prioritize data integrity, SQL compliance, and extreme reliability.

LEARNING PHILOSOPHY

This crash course is designed for rapid architectural understanding. You will not find endless video tutorials here. Instead, you will read the core theory, analyze real-world engineering patterns, and immediately execute your knowledge in the terminal.
