logging_collector is off, but the logging is opening

Hi community,
When I use the postgres, I check the log.(I use the -l open the log)
As you can see, I type code like this:

postgres=# show logging_collector;
 logging_collector
-------------------
 off
(1 row)

postgres=# ^C

Follow the document, when logging_collector is off, there's no log output, but when I check my 'postgres' directory:

[postgres(at)fedora postgres]$ ls
build.sh  logfile  src  startdb.sh  stopdb.sh  update.sh

[postgres(at)fedora postgres]$ cat logfile
2023-07-24 09:54:59.668 CST [35872] LOG:  starting PostgreSQL 17devel on x86_64-pc-linux-gnu, compiled by gcc (GCC) 13.1.1 20230614 (Red Hat 13.1.1-4), 64-bit
2023-07-24 09:54:59.668 CST [35872] LOG:  listening on IPv6 address "::1", port 5432
2023-07-24 09:54:59.668 CST [35872] LOG:  listening on IPv4 address "127.0.0.1", port 5432
2023-07-24 09:54:59.684 CST [35872] LOG:  listening on Unix socket "/tmp/.s.PGSQL.5432"
...

In a word, the log is actually open. (My startup command: pg_ctl -l logfile /home/postgres/postgres/bin/bin/pg_ctl -l logfile -D /home/postgres/postgres/data start)

So It's confuse me, the confilt of logging_collector & logfile.

Can someone give me some advice?
Thanks in advance!

Yours,
Wen Yi
