+= How to install PostGIS 2.0 on Ubuntu 12.10 (''quantal'') from source =
+
+== Prerequisites ==
+Several components are needed, which can either be built from source or installed from pre-built packages, as shown below.
+
+Install prerequisite packages using:
+{{{
+sudo apt-get install build-essential postgresql-9.1 postgresql-server-dev-9.1 libgeos-c1 libxml2-dev libproj-dev libjson0-dev xsltproc docbook-xsl docbook-mathml
+}}}
+
+Optional package for raster support (this is required if you want to build the PostgreSQL extensions):
+{{{
+sudo apt-get install libgdal1-dev
+}}}
+
+== Build PostGIS ==
+{{{
+wget http://download.osgeo.org/postgis/source/postgis-2.0.1.tar.gz
+tar xfvz postgis-2.0.1.tar.gz
+cd postgis-2.0.1
+}}}
+
+PostGIS 2.0 can be configured to disable topology or raster components, using the configure flags `--without-raster` and/or `--without-topology`. The default is to build both. Note that raster is required for the extension installation method for PostgreSQL.
+{{{
+./configure
+make
+sudo make install
+sudo ldconfig
+sudo make comments-install
+}}}
+
+Lastly, enable the command-line tools to work from your shell:
+{{{
+sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/shp2pgsql
+sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/pgsql2shp
+sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/raster2pgsql
+}}}
+
+== Spatially enabling a database ==
+With PostgreSQL 9.1, there are two methods to add PostGIS functionality to a database: using extensions, or using enabler scripts.
+
+=== PostGIS Extension for PostgreSQL ===
+Spatially enabling a database using extensions is a new feature of PostgreSQL 9.1.
+
+Connect to your database using pgAdmin or psql, and run the following commands. To add postgis with raster support:
+{{{
+CREATE EXTENSION postgis;
+}}}
+
+To add topology support, a second extension can be created on the database:
+{{{
+CREATE EXTENSION postgis_topology;
+}}}
+
+=== Enabler Scripts / Template ===
+
+Enabler scripts can be used to either build a template, or directly spatially enable a database. This method is older than the extension method, but is required if the raster support is not built.
+
+The following example creates a template, which can be re-used for creating multiple spatially-enabled databases. Or if you just want to make one spatially enabled database, you can modify the commands for your needs.
+
+PostGIS:
+{{{
+sudo -u postgres createdb template_postgis
+sudo -u postgres psql -d template_postgis -c "UPDATE pg_database SET datistemplate=true WHERE datname='template_postgis'"
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/postgis.sql
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/spatial_ref_sys.sql
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/postgis_comments.sql
+}}}
+
+with raster support:
+{{{
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/rtpostgis.sql
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/raster_comments.sql
+}}}
+
+with topology support:
+{{{
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/topology.sql
+sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/9.1/contrib/postgis-2.0/topology_comments.sql
+}}}
