What is the best replication in Postgres?

Question

PostgreSQL

Friends gave the idea that postgres has automatic switching of masters (a la cluster mode), unlike mysql (where you need to install either an orchestrator or a galley)

The question is - what type of replication is needed in Postgres for automatic switching of masters? Or is a "cluster" mode needed in general, if it exists in general?

Answer 1

postgres has automatic master switching

There's no such thing.
Only external managers (patroni, for example). Well, or in some forks, but this is a question for these forks, and not for postgresql.
