Observable supports direct DB connections [0], but these only work in private notebooks at the moment. At Splitgraph [1] we're building a "data delivery network" (DDN, like a CDN but for databases) that looks like a big Postgres database. It works really well with the Observable Postgres client in private notebooks -- you configure it like you would for any Postgres connection. For public notebooks, you can use our HTTP API for sending SQL queries directly to the DDN. Here's an example [2] using that SQL-over-HTTP API to plot some Covid data.
