PostgreSQL 10 High Performance - Third Edition

By: Enrico Pirozzi

Overview of this book

PostgreSQL database servers have a common set of problems that they encounter as their usage gets heavier and requirements get more demanding. Peek into the future of your PostgreSQL 10 database's problems today. Know the warning signs to look for and how to avoid the most common issues before they even happen. Surprisingly, most PostgreSQL database applications evolve in the same way—choose the right hardware, tune the operating system and server memory use, optimize queries against the database and CPUs with the right indexes, and monitor every layer, from hardware to queries, using tools from inside and outside PostgreSQL. Also, using monitoring insight, PostgreSQL database applications continuously rework the design and configuration. On reaching the limits of a single server, they break things up; connection pooling, caching, partitioning, replication, and parallel queries can all help handle increasing database workloads. By the end of this book, you will have all the knowledge you need to design, run, and manage your PostgreSQL solution while ensuring high performance and high availability

Interacting with the live configuration

There are many ways to change the database's parameters beyond just editing its configuration file and restarting. Understanding these can be critical to reducing server downtime just for routine configuration changes, as well as making sure you're adjusting the parameter you want at the time when you want the change to take effect.

Defaults and reset values

The database has two things that you might refer to as a default, depending on your context. The first type of default is what the server will set the value to if you don't ever change it to the setting the server starts with before it has even read the postgresql.conf file. Starting in PostgreSQL 8.4, you can check...
