 This is a common problem which was not yet addressed well. One solution is
 to use something like this:

 {{{
 db_linked_layers=1,2
 attribute_layer_1_layer_name=test_vinfo_with_db_3d
 attribute_layer_1_database=/home/user/g/LL/user/vector/test_vinfo_with_db_3d/sqlite.db
 attribute_layer_1_database_driver=sqlite
 ...
 attribute_layer_2_layer_name=...
 }}}

 The naming should be improved but the idea is similar to OSM tagging:

 {{{
 emergency=fire_hydrant
 fire_hydrant:type=underground
 fire_hydrant:diameter=1
 ...
 }}}

 Alternative and more universal approach is using JSON as in case of
 G7:v.what. Something like this:

 {{{
 ...
 "dblinks": [
     {
         "number": 1,
         "name": "test_vinfo_with_db_3d",
         "database": "/home/user/g/LL/user/vector/test_vinfo_with_db...",
         ...
     {
 ]
 ...
 }}}

 Also comapre:

 {{{
 g.extension -g
 g.search.modules gradient -j
 }}}
