Version: 2.2 → master

Thanks for the report, I don't think that we should support this by adding a custom expression because currently you can always use django.contrib.postgres.fields.hstore.KeyTransform, e.g. 

Person.objects.annotate(height=KeyTransform('height', 'attributes'))

I don't think that we need to add anything new. IMO, documentating django.contrib.postgres.fields.hstore.KeyTransform should be enough.

It's more complicated for JSONField because nesting multiple KeyTransform() is not so handy.

Thank you! I agree, I had no idea this was available.

Being a first time poster, what do I do now? Should I close this ticket?
