Log message:
    Modify array operations to include array's element type OID in the
    array header, and to compute sizing and alignment of array elements
    the same way normal tuple access operations do --- viz, using the
    tupmacs.h macros att_addlength and att_align.  This makes the world
    safe for arrays of cstrings or intervals, and should make it much
    easier to write array-type-polymorphic functions; as examples see
    the cleanups of array_out and contrib/array_iterator.  By Joe Conway
    and Tom Lane.
