## Problem https://github.com/neondatabase/neon/pull/11515 introduced a bug that some key history cannot be verified. If a key only exists above the horizon, the verification will fail for its first occurrence because the history does not exist at that point. As gc-compaction skips a key range whenever an error occurs, it might be doing some wasted work in staging/prod now. But I'm not planning a hotfix this week as the bug doesn't affect correctness/performance. ## Summary of changes Allow keys with only above horizon history in the verification.
