May I hijack this thread for a related q. I love the public up-to-date hn dataset.

I saw recursive cte blog post..but this doesn't seem to work your hn dataset

Are recursive ctes disabled on this instance or am i doing something wrong?

Done, and now it works perfectly.

what was broken?

This is unclear to me, I will ask the author.

The reason is trivial - I disabled the new feature flag on the playground service long ago (when it was in development). I will enable it back and send an example.
