Godofredo,

Currently OGR does not support this in any organized way.  Basically a layer
is only allowed to have one geometry per feature.  In a datasource, such as
PostGIS, that can have multiple geometries there is one column that is used
and any other geometries are ignored.

There has been some discussion of addressing this case in a more organized
way but there is no action expected in the near future.

Best regards,
