Data Types in PostgreSQL: Bit String Data Types || PostgreSQL Full Playl...

Welcome to Episode #51 of our PostgreSQL Full Playlist! 🎬

In this tutorial, we dive deep into Bit String Data Types in PostgreSQL—BIT(n) and BIT VARYING(n). These types allow you to store and manipulate binary sequences (1s and 0s), perfect for compact data storage like bitmasks, feature flags, and permission sets.

We’ll cover:

• What are BIT(n) and BIT VARYING(n) types?

• The difference between fixed and variable-length bit strings

• How to insert valid/invalid values

• How casting affects storage (padding and truncation)

• Real-world use cases

• Using bitwise operators (AND, OR, XOR, NOT)

• Useful bit string functions like LENGTH() and OCTET_LENGTH()

• Common pitfalls and advanced tips

With full examples and clear explanations, this video is ideal for both beginners and intermediate PostgreSQL learners.
