DB linkage

-----
   There is a very solid DATABASE linkage in GRASS with the db tools.
   DB tools works with Informix, Oracle and Ingress at last count and
   fully implements the "geo-relational" model. I don't want to carp

Could someone tell me where I can find this linkage with Ingres and what it consists of?
