It usually happens when there are disk issues, that's exactly what it is for.

Well, because the customer could recreate (within reason) the original
table definitions, we were able to recover all of his data (12 tables,
including some toasted/compressed).
It's just that matching table and file, and subsequently figuring out
some missing columns which may have been added/removed later,
can be rather timeconsuming and could be made a lot easier (not necessarily
perfect) if that information would have been present in the first page of
a file.
