[HACKERS] Suspicious place in heap_prepare_freeze_tuple()

Hi!

Playing around freezing tuple I found suspicious piece of code:

heap_prepare_freeze_tuple():
...
frz->t_infomask = tuple->t_infomask;
...
             frz->t_infomask &= ~HEAP_XMAX_BITS;
             frz->xmax = newxmax;
             if (flags & FRM_MARK_COMMITTED)
                 frz->t_infomask &= HEAP_XMAX_COMMITTED;

Seems, in last line it should be a bitwise OR instead of AND. Now this line 
cleans all bits in t_infomask which later will be copied directly in tuple.
