GRASS: import PostGIS vector layer into SQLite database

I am working with vector layers (points) composed of more than 100 000 geometries. These layers are originally in a PostGis database and I import them with v.in.ogr, using a formulation like:

v.in.ogr \
    input="PG:host=127.0.0.1 dbname=gisdb user=user password=secret" \

    layer=schema.points \
    output=points \
    -o --overwrite

This command is successful, however, operations with the resulting points layer are remarkably slow. For instance, this layer must be later loaded in R and that operation alone is taking over 3 hours.

After some back-and-forth testing, I identified the problem: v.in.ogr is not saving its output in the internal GRASS SQLite database. Knowing this, I can create a copy of the original output, that is automatically inserted into the SQLite database, e.g.:

g.copy vector=points,points_mirror

Importing the points_mirror layer to R takes 3 minutes instead of 3 hours, for instance.

While mirroring vectors imported with v.in.ogr solves the issue, it is an inelegant solution that also takes up unnecessary space. I would prefer to instruct v.in.ogr somehow to force it to use the SQLite database. I could not find any reference in the manual, is it possible to do?
