I think Josh Berkus' comments in the thread you mentioned are correct:
Actually, I'd say that there's a broad set of cases of people who want
to do a parallel pg_dump while their system is active. Parallel pg_dump
on a stopped system will help some people (for migration, particularly)
but parallel pg_dump with snapshot cloning will help a lot more people.
But you failed to quote the rest of what he said:
So: if parallel dump in single-user mode is what you can get done, then
do it. We can always improve it later, and we have to start somewhere.
But we will eventually need parallel pg_dump on active systems, and
that should remain on the TODO list.
Right, and the reason I don't think that's right is that it seems to me
like a serious potential footgun.
But in any case, the reason I quoted Josh was in answer to a different
point, namely Tom's statement about the limited potential uses.
