postgres failed to deploy due to:

 message: 'devmapper: Error activating devmapper device for ''4310c37b85962b06ab305a8212c1fde0946f2087ba745d823807f7c176bea859'':
            devicemapper: Error running deviceCreate (ActivateDevice) dm_task_run

and the ruby deploy depends on reaching the DB.

so that makes this a dupe of: #17787
