Once the geometry field is created, it is too late, and any attempt to modify 
it will have no effect on how it is serialized.

But if you call AddGeomFieldDefn() (for layers with multiple geometry columns) 
with a geometry field definition that has the SRS set, that should be used too 
to record it in the DB.
