[GRASS-user] PostgreSQL raster and vector import

In addition to my mail yesterday (see below):
The use of PostGIS might be related to the conversation from octobre
but it remains unclear to me how to import raster and is not referred to
in the manual.
My current state seems close to the solution:
r.in.gdal in="PG:dbname=psql_local schema=myschema table=reference_map"
out=region_ref -o --o #load into grass
r.external source="PG:dbname=psql_local schema=myschema
table=reference_map" out=region_ref --o -o #link to grass
But both lead to "ERROR: North must be larger than South"
However, I can view the data in QGIS (loading though db-manager) and it
appears to be ok.
Is Error it a problem of gdal, my data or the grass-modules? And how can
I solve it?
Thanks for any help
