I like this article. Lots of comments are stating that they are "using it wrong" and I'm sure they are. However, it does help to contrast the much more common, "use Postgres for everything" type sentiment. It is pretty hard to use Postgres wrong for relational things in the sense that everyone knows about indexes and so on. But using something like L/N comes with a separate learning curve anyway - evidenced in this case by someone having to read comments in the Postgres source code itself. Then if it turns out that it cannot work for your situation it may be very hard to back away from as you may have tightly integrated it with your normal Postgres stuff.
I've landed on Postgres/ClickHouse/NATS since together they handle nearly any conceivable workload managing relational, columnar, messaging/streaming very well. It is also not painful at all to use as it is lightweight and fast/easy to spin up in a simple docker compose. Postgres is of course the core and you don't always need all three but compliment each other very well imo. This has been my "go to" for a while.
