Error in initializing Postgres in Manjaro Linux system

Question

Here's the step by step commands i applied. I cant seem to start the Postgre database. Any ideas?

step 1:

 sudo pacman -S postgresql vim

step 2:

postgres --version
postgres (PostgreSQL) 16.1

step 3:

echo "en_US.UTF-8 UTF-8" | sudo tee /etc/locale.gen
en_US.UTF-8 UTF-8
➜  ~ sudo locale-gen
Generating locales...
  en_US.UTF-8... done
Generation complete.

step 4:

systemctl status postgresql
