Uh, so VACUUM FREEZE unconditionally freezes all rows, while vacuum just
freezes rows who's xid is older than vacuum_freeze_min_age?  I saw that
in our current docs in reference to VACUUM FREEZE:

	Selects aggressive "freezing" of tuples. Specifying FREEZE is
	equivalent to performing VACUUM with the vacuum_freeze_min_age
	parameter set to zero. The FREEZE option is deprecated and
	will be removed in a future release; set the parameter instead.

Updated patch attached.
