To migrate existing data from a previous major version of PostgreSQL run:
brew postgresql-upgrade-database
This formula has created a default database cluster with:
initdb --locale=C -E UTF-8 /opt/homebrew/var/postgres
For more details, read:
https://www.postgresql.org/docs/14/app-initdb.html
To restart postgresql after an upgrade:
brew services restart postgresql
Or, if you don't want/need a background service you can just run:
/opt/homebrew/opt/postgresql/bin/postgres -D /opt/homebrew/var/postgres

19.1. The PostgreSQL User Account
As with any server daemon that is accessible to the outside world, it is advisable to run PostgreSQL under a separate user account. This user account should only own the data that is managed by the server, and should not be shared with other daemons. (For example, using the user nobody is a bad idea.) In particular, it is advisable that this user account not own the PostgreSQL executable files, to ensure that a compromised server process could not modify those executables.
Pre-packaged versions of PostgreSQL will typically create a suitable user account automatically during package installation.
To add a Unix user account to your system, look for a command useradd or adduser. The user name postgres is often used, and is assumed throughout this book, but you can use another name if you like.
