最近把 Mac OS 從 Monterey 升級到 Ventura 後， Homebrew 安裝的 Postgresql 就跑不起來：
1 2 3 4 5 6
$ brew services info postgresql Warning: Use postgresql@14 instead of deprecated postgresql postgresql@14 (homebrew.mxcl.postgresql@14) Running: ✘ Loaded: ✔ Schedulable: ✘
重啟或重新安裝都沒有用，也沒有明確的錯誤訊息。到 Homebrew 的 log 資料夾下查詢：
1
$ tail /opt/homebrew/var/log/postgres.log
看到錯誤訊息：
1 2
