this, so much. Last time I worked with MongoDB it was with some founder code where he'd scraped sites for data and evolved the code & schema as he found issues. To stop my code from crashing every day, I had to basically write a ton of boilerplate to enforce the schema. I tried to convince him to move to Postgresql, but he was convinced that it would be slow and he'd have to write a lot of boilerplate to deal with it hehe
