Sure enough, there are 26 index entries referencing block 7, which
matches the number of updates into that block that seemed to have
occurred according to pg_class. So those updates definitely happened,
and then *something* made block 7 go away.

What's the platform here --- what kernel, what version exactly,
what hardware and disk subsystem? I think your problem is somewhere
in there ...
