Validate functions/triggers when table definitions change

It'd be amazing if when i change the name of a column or remove it if there were an alert that functions or triggers rely on them so I can correct them before I get errors. I had a function that referenced a column i called nickname to populate a search terms field and i changed it to display_name but i missed a function that builds the search terms and started getting errors in production. would love if the functions were validated and threw errors somehow. Not sure of the actual solution, but that's the problem.
