Data Types in PostgreSQL: Binary (BYTEA) Data Types || PostgreSQL Full P...

📦 Welcome to Episode #48 of our PostgreSQL Full Playlist! In this video, we dive deep into one of the most important and specialized PostgreSQL data types — Binary Data Types, specifically the BYTEA type.

🔍 The BYTEA data type is used to store binary data like files, images, encrypted content, or any non-textual byte stream. We’ll walk you through:

• What is BYTEA and when to use it

• Input formats: Hex vs Escape (with full examples)

• How to insert and retrieve binary data

• Usage of encode() and decode() functions

• How PostgreSQL automatically compresses large binary objects using TOAST

• Important security and performance tips for handling BYTEA values

🎓 Whether you're a database developer, backend engineer, or someone diving into PostgreSQL internals — this video will give you both the theory and hands-on practice to master binary data management in PostgreSQL.
