Thinking of migrating to PostgreSQL? This clear, fast-paced introduction helps you understand and use this open source database system. Not only will you learn about the enterprise class features in versions 9.2, 9.3, and 9.4, you’ll also discover that PostgeSQL is more than a database system—it’s also an impressive application platform.

With examples throughout, this book shows you how to achieve tasks that are difficult or impossible in other databases. This second edition covers LATERAL queries, augmented JSON support, materialized views, and other key topics. If you’re a current PostgreSQL user, you’ll pick up gems you may have missed before.

Apply the psql command-line utility and the pgAdmin graphical administration tool
Explore PostgreSQL tables, constraints, and indexes
Learn powerful SQL constructs not generally found in other databases
Use several different languages to write database functions
Tune your queries to run as fast as your hardware will allow
Query external and variegated data sources with foreign data wrappers
Learn how use built-in replication filters to replicate data
