Hi PostgreSQL Web Team,
My name is Jesús Espino, and I am the author of a recently completed book titled "Deep Dive Into a SQL Query: A Journey Through PostgreSQL's Query Processing."
I would like to request its inclusion in the official PostgreSQL books section (https://www.postgresql.org/docs/books/). This book is a deep-dive technical resource designed to help developers and DBAs understand the internal pipeline of the database.
Here are the details for the entry:
Title: Deep Dive Into a SQL Query
Subtitle: A Journey Through PostgreSQL's Query Processing
Author: Jesús Espino
Publisher: Leanpub
Publication Date: 2026
URL: https://leanpub.com/deep-dive-into-a-sql-query
Description: An in-depth journey through PostgreSQL's query processing internals. It follows a SQL statement through every stage of the pipeline: lexical analysis, parsing, semantic validation, rule-based rewriting, cost-based optimization, and execution. The book is grounded in PostgreSQL's actual source code and explains how the engine manages memory, disk data, and concurrency.
Version covered: 18
I believe this resource will be highly beneficial to the community as it bridges the gap between high-level SQL and database mechanics.
Thank you for your time and for all the work you do for the PostgreSQL project.
Best regards,
Jesús Espino
