Is it possible to delegate aggregation functions to the backing PostgreSQL instance with the PosGIS JNDI datastore?  I am attempting to do aggregations on millions of points and would prefer this happens on the backend.  In particular with the "Collection_Sum" function using the GeoTools FeatureCollection/Function/Filter abstraction.  In stepping through the code I see this function being performed locally.

Thanks.
