This book is your one-stop resource on PostgreSQL system architecture, installation, management, maintenance, and migration. It will help you address the critical needs driving successful database management today: reliability and availability, performance and scalability, security and compliance, cost-effectiveness and flexibility, disaster recovery, and real-time analytics—all in one volume.

Each topic in the book is thoroughly explained by industry experts and includes step-by-step instructions for configuring the features, a discussion of common issues and their solutions, and an exploration of real-world scenarios and case studies that illustrate how concepts work in practice. You won't find the book's comprehensive coverage of advanced topics, including migration from Oracle to PostgreSQL, heterogeneous replication, and backup & recovery, in one place—online or anywhere else.

PostgreSQL is one of the most popular open source object-relational database management systems (ORDBMS). It is based on POSTGRES, Version 4.2, initially developed at the University of California at Berkeley’s Computer Science department. PostgreSQL is based on the Berkeley code and follows the SQL standard, offering various features we will cover in this book.

The PostgreSQL architecture is designed to handle transactions efficiently and maintain data integrity, supporting concurrent sessions. In this chapter, we will learn about the various components of the PostgreSQL internal architecture and their functions.

PostgreSQL follows a typical client/server architecture. The client and server are usually on different hosts and communicate over a TCP/IP network connection. Several core components work together to handle queries, manage data storage, and ensure efficient execution of the query operations.

What You Will Learn:

Install PostgreSQL using source code and yum installation
Back up and recover
Migrate from Oracle database to PostgreSQL using ora2pg utility
Replicate from PostgreSQL to Oracle database and vice versa using Oracle GoldenGate
Monitor using Grafana, PGAdmin, and command line tools
Maintain with VACUUM, REINDEX, etc.

Who This Book Is For:
Intermediate and advanced PostgreSQL users, including PostgreSQL administrators, architects, developers, analysts, disaster recovery system engineers, high availability engineers, and migration engineers.
