las2ogr should work here.

The extra properties are not the case here. The point is that it is not a
vector data.
A point cloud is neither vector nor raster. It is a raw point cloud which
can be processed depending on your needs, to form of vector or form of
raster.

Dumping a point cloud to PostGIS and trying to make a vector sense of it
without any relevant processing has very little sense, IMHO.
