> FerretDB is an open-source proxy, converting the MongoDB wire protocol queries to SQL - using PostgreSQL as a database engine.

Based on this description I'd agree that FerretDB isn't a database itself. However the conversion between the MongoDB wire protocol to SQL queries could have bugs, data resiliency could be an issue if you need to guarantee writes, No guarantees of on-going support, etc.

New db's are always welcome but to use a brand new one in production would be very.... bold.
