How to install PostGIS 2.0 on Ubuntu 13.04 (raring)) 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 libxml2-dev libgeos-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 libgdal-dev
Build PostGIS
wget http://download.osgeo.org/postgis/source/postgis-2.0.7.tar.gz tar xfz postgis-2.0.7.tar.gz cd postgis-2.0.7
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
