Hmm. The patch looks correct as far as it goes. But that function is still a
bit funny. When it compares two identical arrays (or objects), and reaches
the WJB_END_ARRAY token, it will still fall into the code that checks what
the va and vb types are, and compares the last scalar values in that array
again. That's wrong, and will fail if the compiler decides to clobber the
local "va" or "vb" variables between iterations of the do-while loop,
because JsonbIteratorNext() does not set the value when returning
That's an obsolete assumption that once actually applied during development.
Attached revision also adds handling for that case.
