Fai un medico dice "Il tuo sistema è pronto per preparare". Dopo l'installazione con homebrew:
brew uninstall postgres && brew install postgres
Ricevo sempre il seguente errore:
Data page checksums are disabled.
fixing permissions on existing directory /usr/local/var/postgres ... initdb: could not change permissions of directory "/usr/local/var/postgres": Operation not permitted
Warning: The post-install step did not complete successfully
You can try again using 'brew postinstall postgresql'
