I found this post very useful. I'm wondering where I could find others like it?

I recommend Postgres FM podcast, e.g. available as video on Postgres TV yt channel. Good content on its own, and many resources of this kind are linked in the episode notes. I believe one of the authors even helped Gitlab specifically with Postgres performance issues not that long ago.
