子标题：Over 100 recipes to design and implement a highly available server with the advanced features of PostgreSQL
PostgreSQL, often known as simply “Postgres”, is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance.
From hardware selection to software stacks and horizontal scalability, this book will help you build a versatile PostgreSQL cluster that will survive crashes, resist data corruption, and grow smoothly with customer demand. We start with selecting the necessary hardware to handle multiple failure scenarios with redundancy. Then, we discuss how to automate and visualize these checks with Nagios, check_mk, and Graphite. We’ll finally round off by tackling the complex problem of data scalability.
