Anyone interested ?
I saw the code involved, and I think the only way this can happen is if
the index file itself was corrupted by previous operation. How could
that happen elludes me; maybe a previous VACUUM changed a sibling's side
pointer but not the page itself's. This is hard to believe however.
Maybe a partial write of some kind; but WAL should save whole-page
snapshots of the four pages involved, so I don't think the corruption
would survive WAL replay (that part of the code I didn't read however).
Not sure what to do about it. I assume that if you reindex, the problem
disappears and you can't reproduce it again? In any case, please save a
copy of the corrupted index file(s). Would you send it to me?
If you need the file for the index exp_card then I'm going to send you
the file.
