I waited and waited to find Postgres 9.2 with PostGIS(>=2.0). 9.1 was all that ever materialized. If you're happy with Postgres 9.1, you can do the soft upgrade mentioned in the post. You can also roll your own PostGIS if already are using 9.2. Strangely, Linux is the most annoying platform to install Postgres and PostGIS on. (usage wise, it's just fine) Uninstalling Postgres on Ubuntu can lead to some pretty significant troubles (the /etc/ artifacts remain... don't delete them!!! the distribution packages do NOT contain them)
