brew upgrade 하고 나온 postgresql 메세지 연구하자 ㅜㅜ

==> postgresql
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
