Comment (by akaariai):
One possible approach is that we change bulk_create()'s approach to be
"save the objects to the database using fastest method available". We
could add a couple of flags, too, for example signals=True/False and
with_pk=True/False. The defaults would be False and False.
Then we would check if the given database can do a fast bulk-insert, or if
we need to switch to a loop with obj.save(force_insert=True).
I guess the biggest problem is that it might be a bit surprising if
bulk_create doesn't do the insert in bulk. But even then, the current
alternative is to do the insert by a loop of save() calls, and that is
exactly what you will get from the updated bulk_create.
For example in fixture loading it would be very convenient if one could
always call bulk_create(), and get the fastest possible bulk insert for
the given model class and database backend combination.
