PostgreSQL 9.3 will be coming out in beta soon and with that, some who want to experiment with both PostGIS and PostgreSQL 9.3 have asked if they can use PostGIS 2.0. The answer is NO. A lot of major changes happened in PostgreSQL 9.3 that required us to patch up upcoming PostGIS 2.1. These changes were not backported to 2.0 and I personally do not plan to back-port them unless lightning strikes me and I escape unscathed, a big wad of cash falls from the sky, or for some reason we can't make the 2.1 cut before 9.3 comes out. So if you are planning to experiment with PostgreSQL 9.3, PLEASE use PostGIS 2.1 development branch. I will try to make sure we release 2.1 before PostgreSQL 9.3 comes out even if I have to resort to hitting some people over the head with a rubber bat :).
Now some people might say "Isn't it cruel not to support PostGIS 2.0 for 9.3", and my answer is "it's crueler to". The reason is simple. We have limited bandwidth for testing permutations of things and the more permutations of things we support, the dirtier our code base becomes making it harder to maintain and also the less time we can devote to properly testing each permutation. I'd rather say we don't support something than to do a half-hearted job of supporting all.
On a slightly different, but also pragmatic note, package maintainers (except for windows maintainers :)) generally only carry one version of PostGIS per version of PostgreSQL, and I'd rather users getting from packages see our best foot than a two year old aging foot.
Note: that going from PostGIS 2.0 to 2.1 is a soft upgrade so you can install 2.1 on your existing PostgreSQL 9.2 without dump restore and then you should be able to pg_upgrade over to 9.3 if your database is too big to dump restore.
We've got experimental pgRouting windows binaries available for windows PostgreSQL 9.2 32-bit and 64-bit for pgRouting 1.0.7 development branch. More details on our Boston GIS blog page.
The final versions we plan to release with upcoming PostGIS 2.1 PostgreSQL 9.2 on stackbuilder as part of the PostGIS install. Barring no difficulties we'll also have experimental binaries for PostgreSQL 9.3 releases once 9.3 reaches beta.
This version and upcoming pgRouting versions support the PostgreSQL extension model, so if you have postgis already installed, its just an additonal simple step:
The 3rd MEAP update of PostGIS In Action, 2nd Edition will be going out very shortly
to Early Action purchasers. Keep your eyes peeled. Lots of errata corrections in previous chapters and appendix, and one
very VERY new chapter on Raster functions which took a ton of time to write, so hopefully it will be well received. Our progress on the chapters is listed on PostGIS In Action 2nd Edition Chapters and all the ones marked as completed you will find in the MEAP. The ones with paperclips have downloadable code and data which you can click on the paperclip to download.
Regarding Raster, the Raster Function chapter is just merely the tip. You'll see a lot more raster usage in upcoming Relating two or more spatial objects and Raster Processing chapter which we are still fleshing out.
We are immensely grateful to all the early action subscribers who have posted errata or general comments about what can be clarified or examples that don't work. General comments about what specific kinds of examples you'd like to see are also welcome. Your opinions
really influence what we write and make for a better book.
Forget Linux, Forget Unix, Forget MacWhatever, forget Windows, and any other OS you may be using.
Say hello to PostOS. PostOS is built on PostgreSQL technology and fits you like a glove.
The built-in planner watches you type (or stare in confusion) and creates a composite image of what kind of person you are and
what behavior it should emulate. It's integrated monitor display and speakers are used to provide information as well as to watch and hear your every move. The built-in image recognition system (an extension to the PostGIS extension), can distinguish between members of your family and can impersonate them as well and change behavior accordingly.
