+1.  The only point I'm not clear on is the complexity, and I trust you
to cut off at the right point here… meanwhile, I'm still asking for this
little more until you say your plate's full :)

That would be awesome.

Then pg_streamrecv could somehow accept options that make it suitable
for use as an archive command, connecting to your (still?) third-party
daemon?  At this point it'd be pg_walsender :)
