commit    143b54d21d37804707c27edebdbd4410891da133
Author:   Peter Eisentraut <peter_e@gmx.net>

First released in: 11.0

    pg_basebackup: Fix progress messages when writing to a file
    
    The progress messages print out \r to keep overwriting the same line on
    the screen.  But this does not yield useful results when writing the
    output to a file.  So in that case, print out \n instead.
