I think that two releases is not actually that much time to just nuke
the exclusive backup interface.  I would be fine if the docs show the
deprecation more aggressively using a warning section, and we could add
an explicit WARNING message about the matter directly when calling
pg_start_backup and pg_stop_backup.

My 2c.
