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.
A comprehensive series of dependable recipes to design, build, and
implement a PostgreSQL server architecture free of common pitfalls
that can operate for years to come. Each chapter is packed with
instructions and examples to simplify even highly complex database
operations. 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.
Filled with practical, step-by-step instructions and clear
explanations for the most important and useful tasks. This hands-on
guide provides a quick and easy way to back up and restore your

efficiently restore it using PostgreSQL.
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...
