Looks more like a fixed-size (23 byte) repeating pattern. The
sampleblob seems to be this:

 - 7 bytes of header (probably some version information):

        03 00 00 00 00 00 00

 - followed by this pattern of constant-sized 17+6 byte blocks (the
last one lacks the 6-byte thing)

but I never looked at the old db4 blob pattern, so I can't tell
whether it's just a simple extension of the old patterns.
