you need to create a postgis template and load the relevent postgis.sql

say your postgis path is /usr/share/postgresql/8.4/contrib
run this

POSTGIS_SQL_PATH=/usr/share/postgresql/8.4/contrib
sudo -u postgres createdb  -E UTF8 template_postgis1 # Create the template spatial database.
sudo -u postgres createlang  -d template_postgis1 plpgsql # Adding PLPGSQL language support.
sudo -u postgres psql  -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis1';"
sudo -u postgres psql  -d template_postgis1 -f $POSTGIS_SQL_PATH/postgis.sql # Loading the PostGIS SQL routines
sudo -u postgres psql  -d template_postgis1 -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql
sudo -u postgres psql  -d template_postgis1 -c "GRANT ALL ON geometry_columns TO PUBLIC;" # Enabling users to alter spatial tables.
sudo -u postgres psql   -d template_postgis1 -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;"

your database then needs to then be created with the created templete template

sudo -u postgres createdb   database_name -T template_postgis1
