Description
🚨 Think CHAR is simple? Think again!
In this video, we unravel the truth behind CHAR (character) — the fixed-length string type in PostgreSQL.

You’ll learn:

How CHAR(n) pads strings with spaces

Why trailing spaces behave unexpectedly in comparisons

How it differs from VARCHAR and TEXT

Real-world use cases like employee codes and fixed ID formats

Why using CHAR might cause issues you didn’t anticipate — especially with pattern matching and data storage

🔥 This session is perfect for developers, DBAs, and data engineers looking to optimize database design and prevent subtle bugs.

📌 By the end of this tutorial, you'll understand when to use CHAR and when to avoid it — and you'll never make the same mistake twice!

👉 If you're building databases with PostgreSQL or preparing for an interview, this lesson is essential.
