I work on a Postgres fork in my day to day job. Something I’ve found incredibly useful is how adept gpt-4 is with the Postgres code base. So much so that I can ask questions like “show me the definition of to_char” or “explain the fields of RangeTblEntry to me”. If you ask llama2 the same question, you’ll get something incoherent about how RangeTblEntry is a private part of Postgres’s code and that it is ethically wrong to talk about what it does.
