This lecture series is incredibly good. Thank you, Professor Andy Pavlo.
I have been preaching the same for decades. I love how honest you are (blockchain) and how you cut through the distractions of document databases, graph databases, and vector databases, which are just modeling techniques in multi modal databases like Postgres.
I love Postgres and the culture that surrounds it.

Min 53 he has the definitions of UNION and UNION ALL backwards.UNIONS removes duplicates and UNION ALL keeps them.

Seeing this on a Sunday evening. This is so nice. I wish to see how individual people can contribute to DB engines (and the list of business problems related to DB engines; not just some consulting CRUD work)

[@humaidkidwai]
