Based on Amazon reviews and others in the PG community, I would 100% get something like this. High Availability / Fail Over are my biggest concerns with PostgreSQL Database.
So, Packt approached me a few months ago and asked me to put together a very basic series of short step-by-step instructions on backing up PostgreSQL. The title is "Instant PostgreSQL Backup and Restore How-to."
