[PostgreSQL] Uninstall for Mac

brew 를 사용해서 postgresql 을 uninstall 을 하는 방법을 적으려고 한다.

일반적인 방법인 brew uninstall postgresql 로 완벽히 지워지지 않아서 적는다.

brew uninstall postgresql 명령어를 사용해서 지웠는데도 이렇게 남아있다.

limjian@Jians-MacBook-Pro-13 postgres % brew uninstall postgres
Uninstalling /usr/local/Cellar/postgresql/14.1_1... (3,304 files, 43.9MB)

limjian@Jians-MacBook-Pro-13 ~ % cd /usr/local/var/postgres
limjian@Jians-MacBook-Pro-13 postgres % ls
