Shoutout to FerretDB doing God's work.
Putting data from apps that were built for MongoDB into Postgres.

And their lived experience trying to help the MongoDB ecosystem by building an open standard for document databases:
In 2021, we founded FerretDB with a bold vision: to return the document database market to its open source roots by creating the leading open source alternative to MongoDB, built on Postgres.
For years, we tirelessly advocated for an open standard. We built a popular product, collaborated with Microsoft to open source DocumentDB, and held high-level meetings with cloud providers and stakeholders to make the case for a standard that is similar to SQL, but for document databases.
In 2023, a MongoDB VP reached out to me. On a Zoom call, we were threatened with a lawsuit for building a compatible product. Being called a thief by a leader of a (then) $35B company was a moment of stark clarity on MongoDB's opinion about our work and the need for a standard. At the end of that call, I told them the industry would inevitably come together to create the open standard they refused to provide.
Their response? "They would never do that. They are our trusted partners."
Today, the market has spoken. The Linux Foundation has announced the adoption of the DocumentDB project [1] to create an open standard with MongoDB compatibility, the exact thing we were sued for earlier this year. [2]
This is a monumental win for developers and enterprises everywhere. It validates the years of work we've poured into this mission.
It is also telling that MongoDB's SSPL license has been abandoned by Elastic or Redis, the two prominent companies who were initially in favor of MongoDB's attempt to redefine open source. All clear signs that MongoDB's behavior is not appreciated by developers. [...]
