My Postgress database hosted by Railwayapp. My Previous Host and port (Old Database Host name and port) HOST=containers-us-west-36.railway.app PORT=5876

New Database after upgrade i got following Host and port No. 'HOST': 'monorail.proxy.rlwy.net', 'PORT': '42328',

My database migration done properly Still pointing to old database. My deployment still pointing to old database(containers-us-west-36.railway.app PORT=5876).
