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 11 allows you to scale up your PostgreSQL infrastructure. This book takes a step-by-step, recipe-based approach to effective PostgreSQL administration. The book will introduce you to new features such as logical replication, native table partitioning, additional query parallelism, and much more to help you to understand and control, crash recovery and plan backups. You will learn how to tackle a variety of problems and pain points for any database administrator such as creating tables, managing views, improving performance, and securing your database. As you make steady progress, the book will draw attention to important topics such as monitoring roles, backup, and recovery of your PostgreSQL 11 database to help you understand roles and produce a summary of log files, ensuring high availability, concurrency, and replication. By the end of this book, you will have the necessary knowledge to manage your PostgreSQL 11 database efficiently.

Bidirectional replication

Bidirectional replication (Postgres-BDR) is a project that's used to allow 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.

Postgres-BDR aims for eventual inclusion within core PostgreSQL, though knowing that is a long and rigorous process. It also aims to provide working software solutions.

Postgres-BDR aims to allow the nodes of the cluster to be distributed physically, allowing worldwide access to data and allowing for disaster recovery. Each Postgres-BDR master node runs individual transactions; there is no globally distributed transaction manager. Postgres-BDR includes replication of data changes anddata definition language(DDL) changes. New tables are added automatically, ensuring that managing BDR is a low-maintenance overhead for applications.
