Mine as well.

I just managed to dredge up some history here though. Turns out you
explicitly disabled this feature for 9.4 to make room for a future
feature to allow left-joining the target table [0]. Is support for
that feature still desired/planned? (If it's been permanently
abandoned for whatever reason, then maybe it's safe just to revert
158b7fa?)
