[SP] Hola Virginia. Realmente el único español, que yo sepa, soy yo,
así que si no te importa, voy a responder a tu pregunta en inglés

[EN] Hi Virginia, AFAIK, I'm the only Spanish on the list. So, I'm
going to answer your question in english.

Are you sure you loaded all the needed sql files? These are
postgis.sql, spatial_ref_sys.sql and rtpostgis.sql

Best regards,
Jorge
