Hi django fellows!
I've stumbled upon this code in the main branch: (see screenshot)
The usecase is iterating through a queryset with prefetch_related lookups
specified.
Do I understand correctly that multiple database queries happen upon
fetching every chunk, and also that multiple database connections are
required?
If so, than I think it would be better just to prohibit the use of
prefetch_related with QuerySet.iterate
