Yeah, I'd been wondering about that too, but have no clue what's up.
It seems particularly odd that all the failures are in installcheck
not check.

If you want to poke at it, I'd suggest changing the ERROR to PANIC
(it's in bufmgr.c) to cause a core dump, run installchecks till you
get a panic, and then look around in the dump to see what you can find.
It'd be particularly interesting to see what the buffer actually
contains.  Also you could look at the corresponding page of the disk
file (which in theory should be the same as the buffer contents,
since this error check is only made just after a read() ...)
