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.
