the
backport-23.1.x
Previously, the tenant upgrade interlock checkpointed the version attached to the upgrade, when it should have checkpointed the fence version. This made it possible for an upgrade to skip versions. The conditions needed for this are rare, but could be triggered by crashes in the upgrade system or by the autoscaler downscaling a serverless cluster with multiple nodes. Release Note: None Fixes: cockroachdb#104884
