<h3>4.2 Checksum Algorithm</h3>
<p>The checksum is computed by interpreting the input as
an even number of unsigned 32-bit integers: x(0) through x(N).
^The 32-bit integers are big-endian if the
magic number in the first 4 bytes of the WAL header is 0x377f0683 and
the integers are little-endian if the magic number is 0x377f0682.
^The checksum values are always stored in the frame header in a
big-endian format regardless of which byte order is used to compute
the checksum.</p>
<p>The checksum algorithm only works for content which is a multiple of
8 bytes in length. In other words, if the inputs are x(0) through x(N)
then N must be odd.
