It did when I tried it.  I'll test to see what combination of factors
produces that.

Yeah, that's the important one.  I went through the sequence:

1) Try to shut down.

2) be told to run pg_stop_backup()

3) run pg_stop_backup()

4) pg_stop_backup never completes.

Look at the original bug report on this thread; it has the details.  I
think it's still the issue that if no logs are being written (database
is idle) pg_stop_backup does not complete, which I thought we fixed, but
maybe not?
