Hi,

I'm looking for an approach to validate a user provided WKT geometry. The 
obvious answer is to let the spatial backend do the validation, so this 
works:

if geometry is not None:
    geometry = db.executesql("select 
st_geomfromtext('{}');".format(geometry))
except ProgrammingError:
    raise HTTP(404, "Invalid WKT Geometry")

I suspect that is probably pretty robust across backends but am I missing 
something more general?

Cheers,
David
