Overview of this book

PostgreSQL is a powerful, open-source database management system with an enviable reputation for high performance and stability. With many new features in its arsenal, PostgreSQL 14 allows you to scale up your PostgreSQL infrastructure. With this book, you'll take a step-by-step, recipe-based approach to effective PostgreSQL administration. This book will get you up and running with all the latest features of PostgreSQL 14 while helping you explore the entire database ecosystem. You’ll learn how to tackle a variety of problems and pain points you may face as a database administrator such as creating tables, managing views, improving performance, and securing your database. As you make progress, the book will draw attention to important topics such as monitoring roles, validating backups, regular maintenance, and recovery of your PostgreSQL 14 database. This will help you understand roles, ensuring high availability, concurrency, and replication. Along with updated recipes, this book touches upon important areas like using generated columns, TOAST compression, PostgreSQL on the cloud, and much more. By the end of this PostgreSQL book, you’ll have gained the knowledge you need to manage your PostgreSQL 14 database efficiently, both in the cloud and on-premise.

BDR

BDR (Postgres-BDR) is a project aiming to provide multi-master replication with PostgreSQL. There is a range of possible architectures. The first use case we support is all-nodes-to-all-nodes. Postgres-BDR will eventually support a range of complex architectures, which is discussed later.

With Postgres-BDR, the nodes in a cluster can be distributed physically, allowing worldwide access to data as well as DR. Each Postgres-BDR primary node runs individual transactions; there is no globally distributed transaction manager. Postgres-BDR includes replication of data changes such as DML, as well as DDL changes. New tables are added automatically to replication, ensuring that managing BDR is a low-maintenance overhead for applications.

Postgres-BDR also provides global sequences, if you wish to have a sequence that works across a distributed system where each node can generate new IDs. The usual local sequences are not replicated.

One key advantage of Postgres-BDR...
