▶What this book covers
- Chapter 1, First Steps, introduces you PostgreSQL 11; it explains how to download and install PostgreSQL 11, connect to a PostgreSQL server, enable server access to the network or remote users, use graphical administration tools, use PSQL query and scripting tools, change your password securely, avoid hardcoding your password, use a connection service file, and troubleshoot a failed connection.

- Chapter 2, Exploring the Database, demonstrates how to identify the version of the database server you are using, as well as the server uptime. It helps you locate the database server files, the database server message log, and the database's system identifier. It explains how to list a database on the database server, and it contains recipes that let you know the number of tables in your database, how much disk space is used by the database and tables, what the the biggest tables are, how many rows a table has, how to estimate rows in a table, and how to understand object dependencies.

- Chapter 3, Configuration, explains topics such as Reading the Fine Manual (RTFM), how to plan a new database, how to change the parameters in your programs, the current configuration settings, the parameters that are at non-default settings, how to update the parameter file, how to set parameters for particular groups of users, the basic server configuration checklist, how to add an external module into the PostgreSQL server, and how to run the server in power-saving mode.

- Chapter 4, Server Control, provides information about starting the database server manually, stopping the server quickly and safely, stopping the server in an emergency, reloading the server configuration files, restarting the server quickly, preventing new connections, restricting users to just one session each, and pushing users off the system. It contains recipes that help you choose a design for multi-tenancy, as well as recipes that explain how to use multiple schemas, give users their own private database, run multiple database servers on one system, and set up a connection pool.

- Chapter 5, Tables and Data, guides you through the process of choosing good names for database objects. Additionally, it explains how to handle objects with quoted names, enforce the same name, maintain the same definition for columns, identify and remove duplicate rows, prevent duplicate rows, find a unique key for a set of data, generate test data, randomly sample data, load data from a spreadsheet, and load data from flat files.

- Chapter 6, Security, provides recipes on revoking user access to a table, granting user access to a table, creating a new user, temporarily preventing a user from connecting, removing a user without dropping their data, checking whether all users have a secure password, giving limited superuser powers to specific users, auditing DDL changes, auditing data changes, integrating with LDAP, connecting using SSL, and encrypting sensitive data.

- Chapter 7, Database Administration, provides recipes on useful topics such as writing a script where all either succeed or fail, writing a PSQL script that exits on the first error, performing actions on many tables, adding and removing columns in tables, changing the data type of a column, adding and removing schemas, moving objects between schemas, adding and removing tablespaces, moving objects between tablespaces, accessing objects in other PostgreSQL databases, and enabling views to be updated.

- Chapter 8, Monitoring and Diagnosis, provides recipes that answer questions such as whether the user is connected, what they are running, whether they are active or blocked, who they are being blocked by, whether anybody is using a specific table, when the table it was last used, how much disk space is being used by temporary data, and why your queries could be slowing down. It also demonstrates how to investigate and report a bug, produce a daily summary report of log file errors,...

출판사 서평

▶ Preface
PostgreSQL is an advanced SQL database server; it is available on a wide range of platforms and is fast becoming one of the world's most popular server databases with an enviable reputation for performance, stability, and an enormous range of advanced features. PostgreSQL is one of the oldest open source projects; it is completely free to use and was developed by a diverse worldwide community. Most of all, it just works!

One of the clearest benefits of PostgreSQL is that it is open source, meaning that you have a permissive license to install, use, and distribute PostgreSQL without paying anyone any fees or royalties. Additionally, PostgreSQL is well known as a database that stays up for long periods, and requires little or no maintenance. Overall, PostgreSQL provides a very low total cost of ownership.

PostgreSQL 11 Administration Cookbook offers the information you need to manage your live production databases on PostgreSQL. The book contains direct insights into PostgreSQL replication and recovery features from the main author and the 2ndQuadrant team. This hands-on guide will assist developers who are working on live databases, and who are supporting web or enterprise software applications using Java, Python, Ruby, and .NET from any development framework. It's easy to manage your database when you've got PostgreSQL 11 Administration Cookbook at hand.

This practical guide gives you quick answers to common questions and problems, and builds on the author's experience as a trainer, user, and core developer of the PostgreSQL database server.

Each technical aspect is broken down into short recipes that demonstrate solutions with working code, and then explain how and why that works. The book is intended to be a desk reference for both new users and technical experts.

The book covers all the latest features available in PostgreSQL 11. Soon you will be running a smooth database with ease!
