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 10 allows users to scale up their PostgreSQL infrastructure. This book takes a step-by-step, recipe-based approach to effective PostgreSQL administration. Throughout this book, you will be introduced to these new features such as logical replication, native table partitioning, additional query parallelism, and much more. You will learn how to tackle a variety of problems that are basically the pain points for any database administrator - from creating tables to managing views, from improving performance to securing your database. More importantly, the book pays special attention to topics such as monitoring roles, backup, and recovery of your PostgreSQL 10 database, ensuring high availability, concurrency, and replication. By the end of this book, you will know everything you need to know to be the go-to PostgreSQL expert in your organization.

Producing a daily summary of log file errors

PostgreSQL can generate gigabytes of logs per day. Lots of data is good if you want to investigate some specific event, but it is not what you will use for daily monitoring of database health.

In this recipe, we'll see how to perform a post analysis of our log files and get reports (and insights) about what has happened in a given period of time.

A different approach is to perform real-time analysis of queries through the pg_stat_statements extension, which will be covered in the next recipe.

Getting ready

Make sure that your PostgreSQL is set up to rotate log files, for example, daily. I personally prefer to integrate PostgreSQL with rsyslog and logrotate for log management...
