Jacob,
The format of the geometry is based on the shapefile format, and there
is code to decode it in OGR (for the geodatabase driver). I think it
would be hard to construct these geometries properly using SQL, but then
my SQL-fu is weak.
I've never actually worked out how the spatial index works, so updating that
might be quite challenging.
Best regards,
