    Hello, I need to consult with someone who knows PostgreSQL and Ruby. We are being told from AWS that our database will automatically update from version 10.21 to version 14. I would like to know if there are any issues that may arise from this. Will it break our system? We are using an older Ruby on Rails. Programming is primarily Ruby and HAML/HTML Files are on Github. Autoconfiguration is done on Jenkins and Terraform. Thank you, Jeb -
