Master over 100 recipes to design and implement a highly available server with the advanced features of PostgreSQL About This Book * Create a PostgreSQL cluster that stays online even when disaster strikes * Avoid costly downtime and data loss that can ruin your business * Updated to include the newest features introduced in PostgreSQL 9.6 with hands-on industry-driven recipes Who This Book Is For If you are a PostgreSQL DBA working on Linux systems who want a database that never gives up, this book is for you. If you've ever experienced a database outage, restored from a backup, spent hours trying to repair a malfunctioning cluster, or simply want to guarantee system stability, this book is definitely for you. What You Will Learn * Protect your data with PostgreSQL replication and management tools such as Slony, Bucardo, pglogical, and WAL-E * Hardware planning to help your database run efficiently * Prepare for catastrophes and prevent them before they happen * Reduce database resource contention with connection pooling using pgpool and PgBouncer * Automate monitoring and alerts to visualize cluster activity using Nagios and collected * Construct a robust software stack that can detect and fix outages * Learn simple PostgreSQL High Availability with Patroni, or dive into the full power of Pacemaker. In Detail Databases are nothing without the data they store. In the event of a failure - catastrophic or otherwise - immediate recovery is essential. By carefully combining multiple servers, it's even possible to hide the fact a failure occurred at all. 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. It all begins with hardware selection for the skeleton of an efficient PostgreSQL database cluster. Then it's on to preventing downtime as well as troubleshooting some real life problems that administrators commonly face. Next, we add database monitoring to the stack, using collectd, Nagios, and Graphite. And no stack is complete without replication using multiple internal and external tools, including the newly released pglogical extension. Pacemaker or Raft consensus tools are the final piece to grant the cluster the ability to heal itself. We even round off by tackling the complex problem of data scalability. This book exploits many new features introduced in PostgreSQL 9.6 to make the database more efficient and adaptive, and most importantly, keep it running. Style and approach This book contains practical recipes that will help the reader solve real world problems related to high availability in PostgreSQL. Every recipe is explained in detail, with relevant explanations, tips and tricks provided for quicker and easier understanding.

Tammond Dale, a peaceful burg of succor and madness cowers at the whim of Rabbit Rue, who sups upon the souls of the undone. Malicious Rue, spinner of dreams that rend and tempt oblivion to swirl through madness and despair, rules unopposed and unknown, biding 'till his shackles fall to cinders. This town has failed to shrug the churn and plods among the damned, clinging to tattered shreds of former, cliched lives. When providence blows Kyle and his family to the harrowed gulch and into the arms of Adriana, the girl Rue so jealously guards, he too becomes snared within warped visions of insanity and horror. Confused and fatigued by Rue's cruel assault, he unearths clues that lead to Old Town, a hollow bastion of Tammond Dale's uneasy past. But to resist is exhausting, and he withers, and Rue is aided by relentless minions in wisps of swirling shadow. His life, humanity, and realty all hinge on understanding he lacks. His only hope exists beyond time, and the glimmer of escape from chaos it can offer...
