D2 is now open source – a new, modern language that turns text to diagrams
I like it and the comparison site on https://text-to-diagram.com
I just wanted to drop a reference to Burnt Sushi's ERD tool [0]. It only does one diagram type: Entity Relationship Diagram. It's wonderful. Human-first syntax, code comments, and some simple formatting settings like colors and font sizes that help make more complex diagram pleasing and informative.

Recommendations for a CLI-tool to generate DB diagrams?
Only tool I've come across is erd but have not personally used it. We use LucidChart for our ERDs at work. They have an API to export to PNG and to create documents within it. The documentation for the API is dense, but it is something I am hoping to take a hack day or two to try to understand and see if I can automate generating and updating our own ERDs.

Choosing the right abstraction level for SQLite library.
You may want to have a look at squeal that someone mentioned the other day in the comments of this post.

What's your favorite Database EDSL/library in Haskell?
https://github.com/morphismtech/squeal, because, to my knowledge, it's the only option that both maintains deep type safety without losing the expressive power of SQL. It can even typecheck your database migrations. There's even a tool to generate the types of your schema based on an existing database: https://github.com/mwotton/squealgen

Writing a simple Haskell Persistence layer using Generics and Reflection
Yep, https://github.com/morphismtech/squeal does this too.

Practical Haskell, 3rd edition, is out!
If you want an example of a type-safe SQL eDSL in Haskell that doesn't have those problems (and supports more Postgres features than esquelto), I'd recommend https://github.com/morphismtech/squeal.
