Really exciting to see the progress on this project! I'm not sure I understand the update "we are in production." Is this referencing a particular release or a more general statement about adoption?

General statement about adoption. Last time we made a Show HN (9 months ago), it was a POC, running on my local. Now we're used in production by some pretty big companies, which is exciting!

This is a really interesting project I found which could be used to detect plan flips and introspect why the Postgres optimizer chose a certain path. Normally that is opaque to the user.

What do you mean by sloppy but functional?

It lacks focus, pages of different views, with different metrics. Split out arbitrarily. That move around frequently.

It seems like its designed without the guidance of a DB expert, rather just some people who have access to a ton of metrics, but dont know what they are for

It would be awesome if this were to make it in core. Jelte did a bunch of work to improve query protocol changes. Having Postgres accept Otel trace propagation would be a gamechanger for debugging the clients and DB together. Especially since ~80%+ of DB related issues I see come down to some sort of long running open transaction which Postgres knows nothing about server-side.

> Every metric I can find online says that MySQL/MariaDB is more popular than PostgreSQL

What are those metrics? If you're talking about things like db-engines rankings, those are heavily skewed by non-production workloads. For example, MySQL still being the database for Wordpress will forever have a high number of installations and developers using and asking StackOverflow questions. But when a new company or established company is deciding which new database to use for their custom application, MySQL is seldom in the running like it was 8-10 years ago.

Also somewhat surprised. DuckDB traction is impressive and on par with vector databases in their early phases. I think there's a good chance it will earn an honorable mention next year if adoption holds and becomes more mainstream. But my impression is that it's still early in its adoption curve where only those "in the know" are using it as a niche tool. It also still has some quirks and foot-guns that need moderately knowledgeable systems people to operate (e.g. it will happily OOM your DB)
