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!
