It wouldn't. You can have a "hot spare" database via log shipping, but
there is zero chance of allowing the backup to run any independent
transactions. (If it did, its xact counter and pg_clog would get out of
sync with the master, causing all subsequently copied data to be
invalid. AFAICS, even read-only transactions would be problematic.)
Not sure if you are familiar with the Slony project, but that is
probably your best bet for data propagation to a live slave at present.
