Log message:
    This patch, which is built upon the "HeapTupleHeader accessor macros"
    patch from 2002-06-10, is supposed to reduce the heap tuple header size
    by four bytes on most architectures.  Of course it changes the on-disk
    tuple format and therefore requires initdb.

    This overlays cmin/cmax/xmax fields into only two fields.
