Right.

g.region ... to set region boundaries and coordinates,
r.to.vect with feature=point parameter

Spearfish example:
g.region -dp
r.to.vect elevation.dem out=elev feature=point
d.mon x0
d.vect elev
v.db.select elev
cat|value|label
1|1112|
2|1111|
3|1111|
4|1110|
...

The value column contains the elevation.
