Hi Martin,
I tried the commandthat Micha suggested v.db.addcol
map=contour_points_c...@permanent layer=1
columns="rast_value double precision" but this age the following error
v.db.addcol Contour_points_cats col=rast_value DOUBLE PRECISION
Sorry <DOUBLE> is not a valid option
Sorry <PRECISION> is not a valid option
So through the GUI I added a column to the attribute table which gave the
command line out put
v.db.addcol map=contour_points_c...@permanent layer=1 {columns=rast_value
double precision}
cheers!

how did you get this command?
It should be
v.db.addcol map=contour_points_c...@permanent layer=1
columns="rast_value double precision"
