> Should You Use Postgres? Most of the time - yes

This made me wonder about a tangential statistic that would, in all likelihood, be impossible to derive:

If we looked at all database systems running at any given time, what proportion does each technology represent (e.g., Postgres vs. MySQL vs. [your favorite DB])? You could try to measure this in a few ways: bytes written/read, total rows, dollars of revenue served, etc.

It would be very challenging to land on a widely agreeable definition. We'd quickly get into the territory of what counts as a "database" and whether to include file systems, blockchains, or even paper. Still, it makes me wonder. I feel like such a question would be immensely interesting to answer.

Because then we might have a better definition of "most of the time."

SQLite likely dominates all other databases combined on the metrics you mentioned, I would guess by at least an order of magnitude.

Server side. Client side. iOS, iPad, Mac apps. Uses in every field. Uses in aerospace.

Just think for a moment that literally every photo and video taken on every iPhone (and I would assume android as well) ends up stored (either directly or sizable amounts of metadata) in a SQLite db.

Yes it seems like it is absent in this discussion but maybe it should have been “it” the whole time as a default option. I wonder if it could attain similar throughput numbers; bet the article would feel slightly sarcastic then though
