Done, it works.
Unclear how the spurious cat crept in, however.
Restarting from scratch:

v.in.ogr "dsn=/home/paolo/liguria agricola-uso suolo.shp" output=liguria_agricola1
snap=-1 min_area=0.0001 -o

v.db.connect -p liguria_agricola1

GRASS_INFO_MESSAGE(15222,1): Vector map <liguria_agricola1 at alessandra> is connected by:
GRASS_INFO_END(15222,1)
layer <1> table <agricola-uso> in database <liguria_agricola1 cat
/home/paolo/Desktop/spezia/grass/spezia/alessandra/dbf/> through driver <dbf> with
key <suolo>

v.in.ogr dsn=/home/paolo/liguria_agricola_test.shp output=liguria_agricola2 snap=-1
min_area=0.0001 -o

v.db.connect -p liguria_agricola2

GRASS_INFO_MESSAGE(15272,1): Vector map <liguria_agricola2 at alessandra> is connected by:
GRASS_INFO_END(15272,1)
layer <1> table <liguria_agricola2> in database
</home/paolo/Desktop/spezia/grass/spezia/alessandra/dbf/> through driver <dbf> with
key <cat>

So, apparently spaces in file name cause the issue.

All the best, and many thanks.
