Where to find postgresql.log on Manjaro

Question

Using Manjaro, I freshly installed PostgreSQL with an user-defined data-directory. PostgreSQL is running fine, but I can't find the postgresql*.log(s), which I used to find in /var/log/postgresql on my former system. In ksystemlog I've seen an error, that I forced by

select * from non_exist_table;

but I'm wondering, if there is no longer the postgresql*.log.
Thank you!
Here is my postgresql.conf.

With logging_collector=off, the logs will just spew to the stderr of the postmaster process. That could have been redirected to a file, or just going to some tty someplace, or just be thrown away. You would have to look at the code which launches the database server.
