[GRASSLIST:6466] plot points in different color

Dear GRASS users,

I have a point data associated with PostgreSQL table. I would like to
fill the points with RGB color based on their attribute (typical desktop
GIS task).

I used "grassrgb" column in PG table and "d.vect -a" command but it did
not fill them with color. Manual page for "d.vect" says that "-a" option
works only for area type vector data;-(((

How can I fill the points with the color based on their attribute in
GRASS?

Thanks,

Rado
