    Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len). · 234a02b2
    Tom Lane authored
    Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with
    VARSIZE and VARDATA, and as a consequence almost no code was using the
    longer names.  Rename the length fields of struct varlena and various
    derived structures to catch anyplace that was accessing them directly;
    and clean up various places so caught.  In itself this patch doesn't
    change any behavior at all, but it is necessary infrastructure if we hope
    to play any games with the representation of varlena headers.
