Installing PostGISLink para este cabeçalho
PostGIS adds geographic object support to PostgreSQL, turning it into a spatial database. GEOS, PROJ.4 and GDAL should be installed prior to building PostGIS. You might also need additional libraries, see PostGIS requirements.
On Debian/Ubuntu, you are advised to install the following packages: postgresql-x.x, postgresql-x.x-postgis, postgresql-server-dev-x.x, python-psycopg2 (x.x matching the PostgreSQL version you want to install). Please also consult platform-specific instructions if you are on Mac OS X or Windows.

Creating a spatial databaseLink para este cabeçalho
PostGIS 2 includes an extension for Postgres 9.1+ that can be used to enable spatial functionality:
$ createdb <db name>
$ psql <db name>
> CREATE EXTENSION postgis;
The database user must be a superuser in order to run
CREATE EXTENSION postgis;.
GeoDjango does not currently leverage any PostGIS topology functionality.
If you plan to use those features at some point, you can also install the
postgis_topology extension by issuing CREATE EXTENSION
postgis_topology;.
Managing the databaseLink para este cabeçalho
To administer the database, you can either use the pgAdmin III program
() or the
SQL Shell ().
For example, to create a geodjango spatial database and user, the following
may be executed from the SQL Shell as the postgres user:
postgres# CREATE USER geodjango PASSWORD 'my_passwd';
postgres# CREATE DATABASE geodjango OWNER geodjango;
