Big Bad "Upgraded" PostgreSQL

A few years ago, we started a project to upgrade our multi-terabyte database from 8.3 to 8.4. Along the way we encountered a number of different obstacles and roadblocks which caused us to postpone the project, but this past fall we finally made it through phase 1 of the project, which by now had become an upgrade from 8.3 to 9.1. The course of the talk will cover several tools and tactics we had to use to get pg_upgrade to complete successfully, including all the different ways that things blew up on us.
