| After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work. | |
| The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0." | |

| brew unlink postgresql | |
| brew install [email protected] | |
| brew unlink [email protected] | |
| brew link postgresql |
