You're correct that the bug is older. I'm not sure about backporting
the fix to 16 and earlier though, because it depends on BtreeCheckState
having the snapshot member which was only added in commit 5ae2087202af.
It's not a difficult patch -- attached.
I was being cautious and under the impression that the bug had never
been actually encountered by users, but I just noticed that in your
reply from 2 Jun 2025 you mentioned hitting this problem. So maybe we
should bite the bullet ...
Is anybody against backpatching this to 14-16?
(One thing I realized is that the comment for BtreeCheckState->snapshot
says that it's used for the uniqueness test only, but that's no longer
the case. So that needs fixed ...)
