Data Types in PostgreSQL: JSON Data Types || PostgreSQL Full Playlist #55

Welcome to Part 55 of our PostgreSQL Full Playlist! 🎥 In this video, we dive deep into one of the most powerful data types in PostgreSQL — JSON and JSONB.

📌 What You’ll Learn:

• The difference between json and jsonb types

• How PostgreSQL stores and processes JSON data

• Practical examples: inserting, querying, and updating JSON fields

• Using operators like @>, ?, and ->>

• Powerful indexing strategies using GIN, BTREE, and expression indexes

• Working with jsonpath queries for complex lookups

• Handling edge cases like Unicode, nulls, and nested structures

• Real-world best practices and performance tips for working with semi-structured data

PostgreSQL’s support for JSON is incredibly robust, allowing developers to handle flexible data formats while still benefiting from SQL power.

Whether you're a backend developer, database admin, or student, this video will equip you with essential skills for modern data modeling using JSON in PostgreSQL.

Data Types in PostgreSQL: Text Search Data Types || PostgreSQL Full Play...

In this video, we dive deep into Text Search Data Types in PostgreSQL, focusing on the powerful combination of tsvector and tsquery. These types form the foundation of PostgreSQL’s built-in Full-Text Search capabilities, enabling developers to perform fast and accurate text searches directly within the database—without needing external tools.

We begin by exploring the tsvector type, which is used to store normalized searchable content, and learn how to manage lexemes, weights, and positions. Then, we examine the tsquery type, which enables rich search logic using Boolean operators, prefix matching, phrase matching (<->), and more.

This tutorial also includes:

• Creating tables and inserting text data

• Using to_tsvector() and to_tsquery() for normalization

• Matching vectors with queries using the @@ operator

• Improving performance with GIN indexes

• Automatically updating vectors via triggers

• Ranking results using ts_rank

• Highlighting search results with ts_headline

• Debugging with ts_debug

Whether you're building a blog search, product catalog filter, or document search engine, PostgreSQL makes it all possible—natively. This is an essential episode in our PostgreSQL Full Playlist. Don’t forget to like, comment, and subscribe!
