Pongo: Write Mongo but Use Postgres — An interesting idea. Rather than being a database server that ‘speaks’ the MongoDB protocol and uses Postgres on the backend (like FerretDB), Pongo's a PostgreSQL client library that presents a Mongo-like interface to Node developers, so you get to use Postgres but act as if you’re using MongoDB.
