In fact it works with length:

GRASS 6.3.cvs (latlong):~ > v.to.db  -p polbnda_italy_state  op=length un=k col=dummy type=boundary
cat|length
-1|8630.5217187381
1|0
2 categories read from map
0 records selected from table
0 categories read from map exist in selection from table
0 categories read from map don't exist in selection from table
0 records updated/inserted
0 update/insert errors

We fixed that one year ago:

2005-11-30 16:26  markus
        * areas.c, description.html: Wolf Bergenheim: use geodetic length
        for perimeter in LatLong; prettified areas.c with indent

to verify exactly the coastline length for Italy which is given incorrectly in
the ASPRS Grid & datums paper on Italy.
