not all documentation are created equally and postgres is at the extreme end.

cheat sheets, top ten lists, tutorials, courses and sample projects all have their use when it comes to mature projects like postgres (sqlite is similar) to help beginners, advanced and expert users make progress on their work.

with LLMs ability to summarize and re-explain dense documentation, one would hope for all projects to invest heavily in their own documentation to spur easier LLM usage or other writers to provide their own "what i wish i knew" thoughts.
