I think this issue was introduced by the latter, so that was my fault.

One approach I came up with to fix this issue is to rewrite the 
targetList entries of an inherited UPDATE/DELETE properly using 
rewriteTargetListUD, when generating a plan for each child table in 
inheritance_planner.  Attached is a WIP patch for that.  Maybe I am 
missing something, though.
