Modified files:
	src/backend/utils/time: tqual.c 

Log message:
	VACUUM must make sure that a HEAP_MARKED_FOR_UPDATE tuple gets marked
	as either HEAP_XMAX_COMMITTED or HEAP_XMAX_INVALID once the updating
	transaction is gone.  Otherwise some other transaction may come along
	and try to test the commit status of t_xmax later --- which could be
	after VACUUM has recycled the CLOG status for that xact.  Bug introduced
	in post-beta4 bug fix.
