Not those other tools because you can't achieve Postgres functionality with those other tools generally.

Postgres can pretend to be Redis, RabbitMQ, and Kafka, but redis, RabbitMQ, and Kafka would have a hard time pretending to be Postgres.

Postgres has the best database query language man has invented so far (AFAIK), well reasoned persistence and semantics, and as of recently partitioning features to boot and lots of addons to support different usecases. Despite all this postgres is mostly Boring Technology (tm) and easily available as well as very actively developed in the open, with a enterprise base that does consulting first and usually upstreams improvements after some time (2nd Quadrant, EDB, Citus, TimescaleDB).

The other tools win on simplicity for some (I'd take managing a PostgreSQL cluster over RMQ or Kafka any day), but for other things especially feature wise Postgres (and it's amalgamation of mostly-good-enough to great features) wins IMO.

Your comment on Boring Technology (tm) made me smile... At Timescale as you'll see in this blog we are happy to celebrate the boring, there's an awful lot to be said for it :) https://blog.timescale.com/blog/when-boring-is-awesome-build...
