I want to say that this does not appear to be to be an objection. I
think it was just a question. An objection implies that you consider a
change to be incorrect or detrimental, and therefore it should not be
made. In this case, by posing your question in this way:

... the patch was derailed and we ended up not doing anything at all,
and worse, we ended up with a separate thread doing something closely
related but in a way that appears unconnected to this thread. (Worse,
Steven forgot to open a commitfest entry for it, so the patch was lost
in the perpetual pgsql-hackers background noise). I think Masahiko
rejected this patch because it was incorrect without that other patch,
or something like that.

I've marked this[2] entry as returned with feedback now. I would
suggest to Steven to propose this patch again, but this time as a single
patch that does the complete change rather than half here and half
there, keeping Masahiko's closing comments[3] in mind. Once he has such
a patch, he can reopen this commitfest entry as Needs Review (moving it
to whatever the open commitfest is.)

Thanks
