Postgres reopens closed processes on Mac. How to solve?

I tried to terminate Postgres on Mac in various ways. I used commands in the terminal:

-D /usr/local/var/postgres stop

,

services stop postgresql

,

stop postgres

. Did not work. The

-9

command I didn't try, because I read that it was dangerous. The PostgreSQL.pref.pane program, which starts and stops Postgre servers, did not provide a solution for this either. The command

pkill -u postgres

worked for most processes, but over time the processes reopen. Is there a way not to reopen?
