Things to know about Homebrew.
To prevent brew install without updating your existing things.
export HOMEBREW_NO_AUTO_UPDATE=TRUE # Please stop breaking things
export HOMEBREW_NO_INSTALL_CLEANUP=TRUE # I appreciate the gesture, but maybe ask first
Install a software it becomes a Service.
List: $ brew services
Name Status User Plist
postgresql started hhh /Users/hhh/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
redis started hhh /Users/hhh/Library/LaunchAgents/homebrew.mxcl.redis.plist
unbound stopped
Then from the plist file, you can see service’s log file location to debug (StandardOutPath, or StandardErrorPath).
Restart: $ brew services restart postgresql
For example, current latest PostgreSQL is 13 and I want to use PostgreSQL 12.
brew install postgresql@12
brew link --overwrite -f postgresql@12
# maybe need this
cp -rf /usr/local/Cellar/postgresql@12/12.7/include/postgresql/server /usr/local/opt/postgresql@12/include
