Overview of this book

PostgreSQL is an open source database used for handling large datasets (Big Data) and as a JSON document database. It also has applications in the software and web domains. This book will enable you to build better PostgreSQL applications and administer databases more efficiently. We begin by explaining the advanced database design concepts in PostgreSQL 9.6, along with indexing and query optimization. You will also see how to work with event triggers and perform concurrent transactions and table partitioning, along with exploring SQL and server tuning. We will walk you through implementing advanced administrative tasks such as server maintenance and monitoring, replication, recovery and high availability, and much more. You will understand the common and not-so-common troubleshooting problems and how you can overcome them. By the end of this book, you will have an expert-level command of the advanced database functionalities and will be able to implement advanced administrative tasks with PostgreSQL.

Troubleshooting PostgreSQL

In the previous chapter of this book, you learned about some useful extensions that are widely adopted and which can give your deployment a real boost. Following up, you will now be introduced to PostgreSQL troubleshooting. The idea is to give you a systematic approach to inspect and fix your system.

The following topics will be of interest:

  • Approaching an unknown database
  • Gaining a brief overview
  • Identifying the key bottlenecks
  • Handling storage corruption
  • Inspecting broken replicas

Keep in mind that many things go wrong, so it is important to professionally monitor the database.
