Is there a way to return the real type on mutation
for example, a mutation with that add a new note returns note_no_rels type
I understand why is that happens from PostgreSQL perspective
but this makes apollo cache very hard to use
in other projects, when the returning type is the same as query type
simply return the correct will update apollo cache

@0x777 this seems to be an important request. What are your thoughts?
