From what I recall, grass does not store the vector geometries (points) into the database. The points are stored in grass internal format and a link to the attributes in the table is used to get the values (cat column).
Daniel, That's correct ... unless one is using postgis.
So, I don't think inserting x/y coordinates in the table via SQL 'INSERT INTO' will work. For this you should try v.in.ascii or, if your data is in a database, you could use v.in.db. But I don't think that just updating the attibute database will magically create new points
I'll see. I did not know if grass would read the attribute table and put a point at each easting/northing since I added cat values to the table. The worst that could occur is that I dump the postgres table and recreate the map as v.in.ascii.
