 brew postgresql-upgrade-database

To have launchd start postgresql now and restart at login:

 brew services start postgresql

Or, if you don't want/need a background service you can just run:

 pg_ctl -D /usr/local/var/postgres start

=⇒ Summary 🍺 /usr/local/Cellar/postgresql/12.2: 3,218 files, 37.8MB =⇒ Caveats =⇒ krb5 krb5 is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.

If you need to have krb5 first in your PATH run:

 echo 'export PATH="/usr/local/opt/krb5/bin:$PATH"' >> ~/.bash_profile
 echo 'export PATH="/usr/local/opt/krb5/sbin:$PATH"' >> ~/.bash_profile

For compilers to find krb5 you may need to set:

 export LDFLAGS="-L/usr/local/opt/krb5/lib"
 export CPPFLAGS="-I/usr/local/opt/krb5/include"
