I took only a brief look at them, so i may be in a state of
misunderstanding :)
As I understand it, the patent is about generating/composing queries

submitting them to backend, not about query processing in the backend.
So there is not much hope that postgres has done it before, as 99% of
postgres
is concerned with backend activities.
