[GRASS-user] v.external and POSTGIS

[Gustavo Martínez]

Hello all,

I'm starting with POSTGIS and GRASS and I have some problems with  
v.external.
My computer is running Debian 'testing' AMD64 with GRASS 6.2.0, Postgresql  
8.1 and Postgis 1.1.6, all from debian packages.
On Postgres, I have a table named vms with column geometry storing POINTS.  
If I connect from GRASS to the database the connection is successful:

db.tables driver=pg database=host=localhost,dbname=pesca
	public.geometry_columns
	public.spatial_ref_sys
	public.vms

When I use v.external:

v.external dsn='PG:host=localhost user=gumartin dbname=pesca' output=pp  
layer=vms

	Cannot open data source

Can anybody help me with this? What am I doing wrong?
Thanks

que la lluvia caiga suavemente sobre tus campos y,
hasta tanto volvamos a encontrarnos,
