If I turn autovacuum off and instead do an ANALYZE in each test database rather than performing the corruptions, I get reports about problems in pg_statistic. This is on my mac laptop. This rules out the theory that autovacuum is propogating corruptions into pg_statistic, and also the theory that it is architecture dependent.
I wonder whether amcheck is confused by the declaration of those columns
as "anyarray".
