PostGIS 2.1 bundle for PostgreSQL 9.3 Windows is now available on StackBuilder for windows users. You will find both the 32-bit and 64-bit versions. The bundle includes the following features:
PostGIS 2.1 with extensions support for postgis (which has geometry/geography/raster), postgis_tiger_geocoder, and postgis_topology.
pgRouting 2.0.0 with extension support -- just do CREATE EXTENSION pgRouting
address_standardizer, which is needed for better tiger geocoding normalizing. Installed with CREATE EXTENSION address_standardizer
One thing that is different with this packaging is that we are no longer providing a template_postgis database. However if you want your database created for you,
you can check the Create spatial database option which will create a regular old database with all the packaged extensions under the sun created for you.
