▶What this book covers
？ Chapter 1, PostgreSQL 13 Overview, provides an overview of PostgreSQL and its features. You will learn about the new functionalities available in PostgreSQL 13.

？ Chapter 2, Understanding Transactions and Locking, covers one of the most important aspects of any database system: proper database work is usually not possible without the existence of transactions. Understanding transactions and locking is vital to performance, as well as professional work.

？ Chapter 3, Making Use of Indexes, covers everything you need to know about indexes. Indexes are key to performance and are therefore an important cornerstone if you want a good user experience and high throughput. All the important aspects of indexing will be covered.

？ Chapter 4, Handling Advanced SQL, introduces you to some of the most important concepts of modern SQL. You will learn about windowing functions as well as other important current elements of SQL.

？ Chapter 5, Log Files and System Statistics, guides you through administrative tasks such as log file management and monitoring. You will learn how to inspect your servers and extract runtime information from PostgreSQL.

？ Chapter 6, Optimizing Queries for Good Performance, tells you everything you need to know about good PostgreSQL performance. The chapter covers SQL tuning as well as information about memory management.

？ Chapter 7, Writing Stored Procedures, teaches you some of the advanced topics related to server-side code. The most important server-side programming languages are covered and important aspects are pointed out.

？ Chapter 8, Managing PostgreSQL Security, is designed to help you improve the security of your server. The chapter features everything from user management to Row-Level Security (RLS). Information about encryption is also included.

？ Chapter 9, Handling Backup and Recovery, is all about backups and data recovery. You will learn how to back up your data, which will enable you to restore things in the event of a disaster.

？ Chapter 10, Making Sense of Backups and Replication, is all about redundancy. You will learn how to asynchronously and synchronously replicate PostgreSQL database systems. All modern features are covered as extensively as possible.

？ Chapter 11, Deciding on Useful Extensions, describes widely used modules that add more functionality to PostgreSQL. You will learn about the most common extensions.

？ Chapter 12, Troubleshooting PostgreSQL, offers a systematic approach to fixing problems in PostgreSQL. It will enable you to spot common problems and approach them in an organized way.

？ Chapter 13, Migrating to PostgreSQL, is the final chapter of this book and shows you how to migrate from commercial databases to PostgreSQL. The chapter covers the most important databases migrated these days.

출판사 서평

▶ Preface
Thanks to its reliability, robustness, and high performance, PostgreSQL has become one of the most advanced open source databases on the market. This updated fourth edition will help you understand PostgreSQL administration and how to build dynamic database solutions for enterprise apps with the latest release of PostgreSQL, including designing both physical and technical aspects of the system architecture with ease.

Starting with an introduction to the new features in PostgreSQL 13, this book will guide you in building efficient and fault-tolerant PostgreSQL apps. You'll explore advanced PostgreSQL features, such as logical replication, database clusters, performance tuning, advanced indexing, monitoring, and user management, to manage and maintain your database. You'll then work with the PostgreSQL optimizer, configure PostgreSQL for high speed, and move from Oracle to PostgreSQL. The book also covers transactions, locking, and indexes, and shows you how to improve performance with query optimization. You'll also focus on how to manage network security and work with backups and replication while exploring useful PostgreSQL extensions that optimize the performance of large databases.

By the end of this PostgreSQL book, you'll be able to get the most out of your database by executing advanced administrative tasks.
