AFAICT, it is an unused nice idea that Radim had. The vector dblink 
functions in field.c support layer number and name, but I can't find a 
module that allows to set the layer name for a given layer number, it 
seems you have to hand-edit the dbln file. Vector modules don't allow 
(yet?) to select a layer by name instead of number. It is in Radim's 
vector TODO and I would like to add that functionality to GRASS7.
