Hans-Jurgen Schonig - PostgreSQL Replication

Hans-Jrgen Schnig has 15 years of experience with PostgreSQL. He is the CEO of a PostgreSQL consulting and support company called Cybertec Schnig & Schnig GmbH (www.postgresql-support.de). It has successfully served countless customers around the globe.

Before founding Cybertec Schnig & Schnig GmbH in 2000, he worked as a database developer at a private research company focusing on the Austrian labor market, where he primarily focused on data mining and forecast models. He has also written several books about PostgreSQL.

This book is dedicated to all the members of the Cybertec family, who have supported me over the years and have proven to be true professionals. Without my fellow technicians here at Cybertec, this book would not have existed. I especially want to thank Ants Aasma for his technical input and Florian Ziegler for helping out with the proofreading and graphical stuff.

Special thanks also go to my girl, Sonja Stdtner, who has given me all the personal support. Somehow, she managed to make me go to sleep when I was up late at night working on the initial drafts.

Jeff Lawson has been a user and fan of PostgreSQL since he noticed it in 2001. Over the years, he has also developed and deployed applications for IBM DB2, Oracle, MySQL, Microsoft SQL Server, Sybase, and others, but he has always preferred PostgreSQL because of its balance of features and openness. Much of his experience has spanned development for Internet-facing websites and projects that required highly scalable databases with high availability or provisions for disaster recovery.

Jeff currently works as the director of software development at FlightAware, which is an airplane tracking website that uses PostgreSQL and other pieces of open source software to store and analyze the positions of thousands of flights that fly worldwide every day. He has extensive experience in software architecture, data security, and networking protocol design because of his roles as a software engineer at Univa/United Devices, Microsoft, NASA's Jet Propulsion Laboratory, and WolfeTech. He was a founder of distributed.net, which pioneered distributed computing in the 1990s, and continues to serve as the chief of operations and a member of the board. He earned a BSc in computer science from Harvey Mudd College.

Jeff is fond of cattle, holds an FAA private pilot certificate, and owns an airplane in Houston, Texas.

Maurcio Linhares is a technical leader of the parsing and machine learning team at The Neat Company. At Neat, he helps his team scale their solutions on the cloud and deliver fast results to customers. He is the creator and maintainer of async, a Scala-based PostgreSQL database driver (https://github.com/mauricio/postgresql-async), and has been a PostgreSQL user and proponent for many years.

Shaun M. Thomas has been working with PostgreSQL since late 2000. He has presented at Postgres open conferences in 2011, 2012, and 2014 on topics such as handling extreme throughput, high availability, server redundancy, failover techniques, and system monitoring. With the recent publication of Packt Publishing's PostgreSQL 9 High Availability Cookbook , he hopes to make life easier for DBAs using PostgreSQL in enterprise environments.

Currently, Shaun serves as the database architect at Peak6, an options trading firm with a PostgreSQL constellation of over 100 instances, one of which is over 15 TB in size.

He wants to prove that PostgreSQL is more than ready for major installations.

Tomas Vondra has been working with PostgreSQL since 2003, and although he had worked with various other databasesboth open-source and proprietaryhe instantly fell in love with PostgreSQL and the community around it.
