Nice guess, but that's unfortunately not it. I get the same message with:

GRASS 6.3.svn (spearfish60):~ > g.copy vect=roads at PERMANENT,myroads

GRASS 6.3.svn (spearfish60):~ > v.db.connect -p myroads
Vector map <myroads at user1> is connected by:
layer <1> table <myroads> in database 
</home/mlennert/GRASS/DATA/spearfish60/user1/dbf> through driver <dbf> 
with key <cat>


I also get the same result with a map fields at user1 connected to a 
postgresql table.

BTW, Martin: I like the highlighting of the queried feature in the edit 
mode. Could this also be activated in the display mode (which maybe 
should be called "query" mode ?) ?
