New description:
When using bulk_create it would be nice to support `ON CONFLICT DO
NOTHING`, which allows existing rows to be included in the `bulk_create`
call, e.g:
{{{#!python
Comment.objects.create(name='test', text='test')
Comment.objects.bulk_create(Comment(name='test', text='test'),
on_conflict=IGNORE) # Does not throw an exception
}}}
All the databases we support have syntax for this, as well as
updating/replacing fields.
This is a spin-off of https://code.djangoproject.com/ticket/28641, just
including the ON CONFLICT idea which is backwards-compatible and would be
easier to implement than the others.
