That's somewhat surprising, but then again, maybe not. Thanks, I'll take note of that.
For anyone else, I also remember PostgresSQL manual/docs being very high quality, so that might be worth reading just to better grok SQL/relational DB topics.
If you're digging into sqlalchemy and enjoying it, you would probably enjoy the source of Ecto, the kinda-sorta-but-not-really ORM that's commonly used with Elixir.
