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
