Re: BUG #16416: unable to start the server with pg_CTL

Hi,

Don't change the permissions manually as it may break your configuration.
You may stop and start the service by two ways:

1. sudo su - postgres (assuming your database superuser account is
'postgres')
and execute pg_ctl commands:
pg_ctl -D /Library/PostgreSQL/12/data stop
pg_ctl -D /Library/PostgreSQL/12/data start

2.
sudo launchctl unload
/Library/LaunchDaemons/com.edb.launchd.postgresql-12.plist
sudo launchctl load
/Library/LaunchDaemons/com.edb.launchd.postgresql-12.plist
