Yes, I was referring to imessages and dynshmem.

I'm not sure, either. It would be nice if there were a way to create
a general facility here that we could then build various applications
on, but I'm not sure whether that's the case. We had some
back-and-forth about what is best for replication vs. what is best for
vacuum vs. what is best for parallel query. If we could somehow
conceive of a system that could serve all of those needs without
introducing any more configuration complexity than what we have now,
that would of course be very interesting. But judging by your
comments I'm not very sure such a thing is feasible, so perhaps
wait-and-see is the best approach.
