[GRASS-user] How update vector layers?

[Thybério Luna Freire]

The great problem in create a new map is that there is a database with rules
of integrity. If the table sugarcane is linked to other table by
primary/foreign keys i can't simply delete it and put the new table in your
place. This is my problem. I have to mantain the table sugarcane and keep
updating it, when necessary.
