This project provides a PostgreSQL extension that adds support for geographic objects
In other words, PostGIS "spatially enables" the PostgreSQL database engine, allowing it to be used as a backend spatial database for GIS (Geographic Information Systems), similar to Oracle's Spatial extension or ESRI's SDE.
There are now several open source tools which work with PostGIS. The uDig project is working on a full read and write desktop environment that can work with PostGIS directly.
To install this extension on your PostgreSQL server, untar the PostGIS tarball in the 'contrib' directory of your PostgreSQL source tree, and run the following commands:
tar xvf postgis-0.9.0.tar
createlang plpgsql yourtestdatabase
psql -d yourtestdatabase -f postgis.sql
psql -d yourtestdatabase -f spatial_ref_sys.sql
