I'm upgrade the bosh deployment of concourse from 3.14.1 to 4.2.1 and receiving this error in /var/vcap/sys/log/atc/atc.stderr.log:
failed to migrate database: 1 error occurred:
* Migration '1533136021_upsert_uniqueness.up.sql' failed: 2 errors occurred:
* Transaction CREATE UNIQUE INDEX worker_task_caches_uniq
ON worker_task_caches (job_id, step_name, worker_name, path) failed, rolled back the migration
* pq: could not create unique index "worker_task_caches_uniq"
