I think that was spurious. It looked good when we looked at it yesterday.
The rest that failed seemed unrelated and was also taking on my SSL patch
too.
I talked to Andres about the possibility of torn reads in the pg_class
stats but those are all 4-byte columns so probably safe. And in any case
that's a pre-existing possibility just more likely (if it's possible at
all) by frequent truncates.
