[GRASSLIST:4170] g.remove / v.surf.idw

hello, something is confusing me. as i reported yesterday i can't remove
vector files where the attributes are stored in postgresql db.

now i tried to interpolate the data and get the following:

GRASS 5.7.0 > v.surf.idw in=temp200012311800 out=temp200012311800
v.surf.idw:
WARNING: Vector used instead of sites.
dbname=sabine,: no such driver available
WARNING: Cannot open driver 'dbname=sabine,'
ERROR: Cannot open database host=..., by driver dbname=sabine,
                                                                                Mapset
<sabine> in Location <oetztal>

but d.vect temp20001231180 works !!!!

the entry in /grassdata/vector/temp200012311800/dbln is:

1 temp200012311800 cat host=..., dbname=sabine, user=sabine, password=... pg

thanks for help, sabine
