I'm trying this out today, and indeed is very slow, much slower than
building the topology, which is surprising to me.

A look at database activity shows that the command (v.out.postgis -l)
is writing _simple_ features in the output layer.  Do you have an idea
about how to skip that part ? (TopoGeometry would be enough for PostGIS
to reconstruct the SFS on demand).
