Overview of this book

PostgreSQL is one of the most popular open source database management systems in the world, and it supports advanced features included in SQL standards. This book will familiarize you with the latest features in PostgreSQL 11, and get you up and running with building efficient PostgreSQL database solutions from scratch. Learning PostgreSQL, 11 begins by covering the concepts of relational databases and their core principles. You’ll explore the Data Definition Language (DDL) and commonly used DDL commands supported by ANSI SQL. You’ll also learn how to create tables, define integrity constraints, build indexes, and set up views and other schema objects. As you advance, you’ll come to understand Data Manipulation Language (DML) and server-side programming capabilities using PL/pgSQL, giving you a robust background to develop, tune, test, and troubleshoot your database application. The book will guide you in exploring NoSQL capabilities and connecting to your database to manipulate data objects. You’ll get to grips with using data warehousing in analytical solutions and reports, and scaling the database for high availability and performance. By the end of this book, you’ll have gained a thorough understanding of PostgreSQL 11 and developed the necessary skills to build efficient database solutions.

Alternative drivers for PostgreSQL

In this section, we will take a closer look at two other PostgreSQL libraries for Python. The first one, pg8000, also implements the DB-API 2.0. This makes it very similar to Psycopg 2. The difference is that it's not dependent on the libpq library, and is written entirely in Python. This makes the library very lightweight, and applications that would use it are easily portable.

The second one, asyncpg, doesn't implement the Python DB-API. It uses a binary protocol to communicate with a PostgreSQL database and asynchronous API in the applications. This makes it possible to create very fast database applications that perform a great amount of commands in a short time.
