Comment (by traianstanev):
While this patch probably fixes the problem, it will make queries by ID
slow, since it will trigger generic SQL evalauation. A better fix would
probably be to not optimize away the filter in the case of an aggregate
query on a non-feature class. There are two code paths in the provider for
aggregates, one is optimized for geometry-based classes and the other is
generic, and you are probably hitting a bug in the generic code path.
