It looks like you don't have PostGIS loaded. This command runs
successfully in a PostGIS-enabled database.

The file names are lwpostgis.sql and spatial_ref_sys.sql and they
must be loaded in that order because the former creates the table
that the latter populates. Also, you'll need install PL/pgSQL
(e.g., with "createlang plpgsql dbname") before loading lwpostgis.sql.
For more information see the Installation chapter of the PostGIS
documentation.

If you continue to have trouble with PostGIS then you might get
more help on the postgis-users mailing list.
