Which still demonstrates that they aren't exact images.  I'd still like
to see the pg_filedump output though ...

Do you by any chance still have 000000010000042200000058 and
000000010000042200000059 archived?  If so it would be useful to
look at the first dozen lines of "od -x" dump of each of them.
