Howdy folks! I finally got the slides up for the “Big Bad `Upgraded` Postgres” talk which I gave at PGCon 2012 (and previously at PGDay DC). The talk walks through a multi-terrabyte database upgrade project, and discusses many of the problems and delays we encountered, both technical and non-technical. I think the slides stand up pretty well by themselves, but you can also find out some additional info on my co-worker Kieth’s blog, where he has also chronicaled some of the fun times we’ve had along the way. He also has some posts on benefits we’ve seen since upgrading. Anyway, slides are on my slideshare page, please have a look.
