M1Mac PostrgreSQLが起動しない時の対処方法

エラー内容

久しぶりにPostgreSQLを起動しようとしたらこんなエラーが。。

$ brew services start postgres
Bootstrap failed: 5: Input/output error
Try re-running the command as root for richer errors.
Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/****/Library/LaunchAgents/homebrew.mxcl.postgresql.plist` exited with 5.

対処方法

1、postmaster.pidを削除

M1チップの方は多分こっちでOK↓

$ rm /opt/homebrew/var/postgres/postmaster.pid

または

$ rm /usr/local/var/postgres/postmaster.pid 

２、PostgreSQLを起動

$ brew services start postgresql

or

$ brew services restart postgresql
