// executing. func (p *Manager) Unprotect(ctx context.Context, job *jobs.Job) error { return p.db.Txn(ctx, func(ctx context.Context, txn *kv.Txn) error {
I think you can simplify this to:
return job.Update(ctx, nil /* txn */, func(txn *kv.Txn, md jobs.JobMetadata, ju *jobs.JobUpdater) error {
// check the job details here etc
})

Yes good point, should have done this much earlier
Done.

Fixes: cockroachdb#92493 Previously, we added the protected timestamps manager into the jobs frame work, which made it easier to automatically add and remove protected timestamps for jobs. Unfortunately, the Unprotect API when invoked from a clean up function never properly refreshed the job. Which could lead to a race condition trying to remove protected timestamps for schema changes. To address this, the Unprotect function will take advantage of the job update function to confirm that a refreshed copy does have protected timestamps set. Release note: None
