In this tutorial, we dive deep into Enumerated (ENUM) Data Types in PostgreSQL – one of the most powerful ways to enforce data integrity and readability in your database schema. 🎯

You’ll learn how to create and use ENUM types to define columns with a fixed set of valid values, like moods, statuses, or categories. We’ll walk through step-by-step examples showing how to:

• Declare ENUM types using CREATE TYPE

• Use ENUMs in tables with INSERT and SELECT

• Understand ENUM ordering and comparison operators

• Avoid type mismatches and safely cast ENUMs

• Add or rename ENUM values using ALTER TYPE

• Inspect ENUM values via PostgreSQL system catalogs

We also cover type safety, implementation details, and best practices when deciding between ENUMs and lookup tables.

Whether you're a PostgreSQL beginner or brushing up on advanced data types, this video is a must-watch to strengthen your schema design skills.
