Only that it isn't. It's stored in PGPROC. This criticism is true of
the progress reporting patch, but a quick scan of the thread doesn't
show authors of the wait events patch participating there.

I don't think so. Afaics the proposed patch tried to do too many things
at once, and it's authors didn't listen well to criticism. Trying to go
back to that seems like a surefire way to have nothing in 9.6.
