PostgreSQL 14 Internals

This is a short note to inform that we are translating my book “PostgreSQL 14 Internals,” recently published in Russian. Liudmila Mantrova, who helped me a lot with the editing of the original, is working on the translation, too. My gratitude to her is beyond words.

The book is largely based on the articles I’ve published here and training courses my colleagues and I are developing. It dives deep into the problems of data consistency and isolation, explaining implementation details of multiversion concurrency control and snapshot isolation, buffer cache and write-ahead log, and then moves on to the twists and turns of the locking system. The book also covers the questions of planning and executing SQL queries, including the discussion of data access and join methods, statistics, and various index types.

The book is freely available in PDF. The translation is in progress, and for now only Part I of the book is ready. Other parts will follow soon, so stay tuned!
