Thanks for the work, Hanada-san and KaiGai-san!

Maybe I'm missing something, but did we agree to take this approach, ie, 
"join push-down" on top of custom join?  There is a comment ahout that 
[1].  I just thought it'd be better to achieve a consensus before 
implementing the feature further.

Is that something like "UPDATE foo ... FROM bar ..." where both foo and 
bar are remote?  If so, I think it'd be better to push such an update 
down to the remote, as discussed in [2], and I'd like to work on that 
together!

Sorry for having been late for the party.
