Data Types in PostgreSQL: XML Data Types || PostgreSQL Full Playlist #54

In this video (#54 of our PostgreSQL Full Playlist), we dive deep into the XML Data Type in PostgreSQL — a powerful and structured way to store and process XML content directly in your database!

We start by exploring how the xml type differs from regular text, including its built-in validation for well-formed XML and compatibility with XML functions like xmlparse, xmlserialize, and xpath.

You’ll learn:

• How to insert XML documents and fragments using XMLPARSE

• PostgreSQL-specific shorthand syntax for XML data

• How to convert XML back into text format using XMLSERIALIZE

• Encoding best practices to avoid client-server issues

• How to query XML using xpath() for data extraction

• Workarounds for indexing XML using full-text search

• Checking whether a stored XML value is a document or content fragment

This video also covers best practices, potential pitfalls, and performance tuning advice when working with XML data in PostgreSQL.

Whether you're building APIs, handling metadata, or managing config files — XML in PostgreSQL is a must-have tool in your toolkit. Don't forget to watch till the end and subscribe for more database tutorials!
