Hola! estoy intentando cargar manualmente el raster support y estoy
ejecutando el rtpostgissql que trae el postgis2.0
Pero al ejecutarlo me tira que no existe la funcion box2d(raster)
Alguna idea de que puede estar pasando?
Gracias!
PD: Escribí en español porque me pareció ver que son de españa y yo en
realidad hablo en español.
saludos!
Virginia
