Just thought I would update this myself. Last night I managed to have a chat with some people about this on IRC. Turns out we're in pretty good shape. We already know about the changes to implicit casting and we have always used UTF-8 for encoding, too. So the changes from 8.4 don't seem to be of a worry for us. (I am sure that we will find SQL hidden in our app somewhere that will need to be modified for implicit casting...and we'lljust fix those as we find them.) Otherwise it seems like a simple case of using the 9.04 pg_dump / (pg_dumpall) application and restoring. I also read chapters 15 / 24 of the excellent documentation about running both 8.1 and 9.04 at the same time and migratinga database at a time. So, I suppose unless there is something obvious, (to someone else) - we have all the information we need.
