Hi! Let's see if someone can answer my question.
In a default PostgreSQL 13 installation, starting the server starts a process called "logical replication launcher". I know what logical replication is but I don't know what this process does on the server. Even if you change the default setting of wal_level to minimal, the process continues to start after the server is restarted so that it takes the change in the wal_level parameter. ¿? Thanks to all!
