PostgreSQL Administration Cookbook, 9.5/9.6 Edition - Third Edition

Overview of this book

PostgreSQL is a powerful opensource database management system; now recognized as the expert's choice for a wide range of applications, it has an enviable reputation for performance and stability. PostgreSQL provides an integrated feature set comprising relational database features, object-relational, text search, Geographical Info Systems, analytical tools for big data and JSON/XML document management. Starting with short and simple recipes, you will soon dive into core features, such as configuration, server control, tables, and data. You will tackle a variety of problems a database administrator usually encounters, from creating tables to managing views, from improving performance to securing your database, and from using monitoring tools to using storage engines. Recipes based on important topics such as high availability, concurrency, replication, backup and recovery, as well as diagnostics and troubleshooting are also given special importance. By the end of this book, you will have all the knowledge you need to run, manage, and maintain PostgreSQL efficiently.

Hot logical backups of one database

Logical backup makes a copy of the data in the database by dumping the content of each table as well as object definitions for that same database (such as schemas, tables, indexes, views, privileges, triggers, constraints, and so on).

How to do it...

The command to do this is simple. The following is an example using a database called pgbench:

pg_dump -F c pgbench > dumpfile

Or, you can use the following command:

pg_dump -F c -f dumpfile pgbench

You can also do this through pgAdmin 4, as shown in the following screenshot:
