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.

Introduction

First set up access rules into the database server. PostgreSQL allows you to control access based upon the host that is trying to connect, using the pg_hba.conf file. You can specify SSL connections if needed, or skip that if the network is secure. You can specify the use of SCRAM authentication using 256 bit keys, as well as many other mechanisms.

Next set up the role and privileges for accessing your data. Databases are mostly used to store data with several restrictions on how it can be used. Some records or tables can only be seen by certain users, and even for those tables that are visible to everyone, there can be restrictions on who can insert new data or change the existing data. All of this is managed by a privilege system, where users are granted different privileges for different tables or other database objects, such as schemas or functions.

It is good...
