I have applied a fix in 6.4/6.5/7 SVN to db.out.ogr to also support attribute
export in case of line and area vectors.

In SVN (r55589) I have added support for multilayers. Please try. Hence it
would be now:

# to export table connected to vector map as layer 2:
db.out.ogr input=allpairs1 layer=2
dsn=/home/dof1985/Grass_projects/allpairs.csv format=CSV
