1) I don't think this should be verbose output. Having a program sit
there "doing nothing" for no apparent reason is just horrible UI design.

2) I think it'd be useful to have a way to get the status of a running
checkpoint. The checkpointer already has that info, and I think it might
even be in shared memory already. If there was a function that reported
checkpoint status pg_basebackup could poll that to provide users with
live status. That should be a separate patch though.
