>> also same is true the other way around, depending on you application you can go redis only

Really the primary reason not to try stuff like this is (at least for me), feel that I won't paint myself into a corner with Postgres. I can always add a table here or a join there and things will work. If I need columnar, I use ClickHouse and NATS for messaging. I know these well but still gravitate toward Postgres because I feel it can grow in whatever direction is needed. However, it is true, I have thought about trying to just use NATS KV and make all services stateful receiving notifications when things change. It does seem that it could massively simplify some things but expect there could be some sharp edges in the face of unknown requirements. If one could just design for exactly the problem at hand it would be different but it never seems to work out like that.
