> 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."
