The new name more accurately relects the effects of this flag on a requested checkpoint. Checkpoint-related log messages (i.e., those controlled by the log_checkpoints configuration parameter) will now say "flush-unlogged" instead of "flush-all", too. This is preparatory work for a follow-up commit that will add a FLUSH_UNLOGGED option to the CHECKPOINT command.
