It's imo too large a feature for that:
63 files changed, 5255 insertions(+), 618 deletions(-)
in addition there's a bunch of followup commits fixing
things. There'll be a significant number of conflicts when applying this
to 9.4.

More importantly it breaks the catalog compatibility, i.e. you can't
patch postgres and then continue with an existing data directory.
