This series fixes a bug in `appending_hash<row>` that caused it to ignore any cells after the first NULL. It also adds a cluster feature which starts using the new hashing only after the whole cluster is aware of it. The series comes with tests, which reproduce the issue.
Fixes #4567
Based on #4574
"
