FAQ

What if the book isn’t what I expected it would be?: The Art of PostgreSQL is a book that teaches SQL to application developers. If it's not of any value to you, then just say so and I'll refund you, no questions asked.
I bought the book, and I'm confused. What now?: The content of the book is available as a PDF and ePub file, and you can also download the SQL queries. The content is available over at https://members.theartofpostgresql.com/courses/the-art-of-postgresql/ from your student dashboard.
I bought a previous edition. Do I get the 2026 update?: Yes — the update is free for all existing purchasers. Log into your ThriveCart account, open the lesson, and download the updated PDF and ePub directly.
What does the book cover, and what do the courses cover?: The book table of contents lists all 9 parts and 57 chapters — from SQL foundations through advanced query patterns and data architecture. The course curriculum covers 6 courses and 48 modules across Core, Advanced, and Architect tiers, with hands-on SQL labs on real datasets.
Is SQL still relevant now that AI writes queries?: Yes — here is why understanding SQL matters more than ever, even when AI generates the code.
Is there any DRM?: No. There isn't even watermarking on the PDF. You own what you buy. The sources of data selected for the book are all available with Open Data types of licenses, and the book itself is copyright Dimitri Fontaine. All rights reserved.
Any other questions?: Contact me by email and just ask! I will do my best to answer you.
