query set sql update to change different values by different keys

[Brillgen Developers]

Database backends like Postgresql support doing multiple value update for the same field in different rows using a single update query. Please see this sample below:

Example:
Currently:

Books.objects.all().update(price=10)

Proposed (syntax can vary):

Books.objects.all().update({'pk': 1, 'price': 10}, {'pk': 2, 'price': 25}])

Idea is to do it in sql for performance reasons but still use the ORM and not use a raw database connection.

However, such an interface is not exposed via the Django ORM. Would this be accepted as a patch? if so, would a list dictionary with the various fields:values to be updated be a good way to provide the input to ORM
