Interesting. This can be done at the terminal with ogr2ogr, but
requires the -update switch. ogr2ogr requires the -update switch to
add a layer to a SpatiaLite file, but not to PostGIS. Hence, writeOGR
can add layers to PostGIS but not to SpatiaLite.

I don't think there's any way to pass the -update switch via writeOGR,
as it is not a dataset creation option or layer creation option.
