Pushed, thanks for reviewing! In the event I decided to back-patch to
v18, where these fixes could protect pg_verifybackup against tar files
it can't handle. In older branches the astreamer (nee bbstreamer)
logic only exists inside pg_basebackup, and IIUC that's not really
exposed to tar files that weren't made by our own code. So I did
not bother with back-patching further, though it'd be possible to
do that if someone knows a scenario where it'd matter.
regards, tom lane
