 Finally, CartoDB depends on a geospatial database template named
-`template_postgis`. In the example script below (can be saved for examples as `template_postgis.sh`), make sure that the

-Before executing the script, change to the postgres user:
-```bash
-sudo su - postgres

-Alternatively, you may run the lines of the `template_postgis.sh` script one by one by entering Postgres as follows:

 ### Raster import support
 Raster importer needs `raster2pgsql` to be in your path. You can check whether it's available by running `which raster2pgsql`. If it's not, you should link it: `$ sudo ln -s /usr/local/src/postgis-2.1.2/raster/loader/raster2pgsql /usr/bin/`.
 
-Access to temporary dir is also needed. Depending on your installation you might also need to run `chown 501:staff /usr/local/src/postgis-2.1.2/raster/loader/.libs` (maybe replacing `501:staff` with your installation /usr/local/src/postgis-2.1.2/raster/loader/ group and owner).
