I recently got the opportunity to take a look at Learning Heroku Postgres, a new book by Patrick Espake that seems intended to help new PostgreSQL database administrators get their data into the cloud. The chapters are short, concise, and the questionnaires at the end are a nice touch. But do they hit the mark? Almost.
Before I get too far into this review, I should point out that Heroku is a proprietary service that presents a modular deployment system for various programming languages, applications, administration, monitoring, and other related services. Though there are free hobby-level instances for most modules, it is a commercial platform which provides SAAS (Software as a Service) across multiple geographic locations. In order to leverage it properly, I recommend these hobby-level instances only for experimentation.
