自分用のメモに書いていたつもりだったのですが、たくさんのスターを頂けてとても嬉しいです。
と同時に、書きかけで中途半端な状態のドキュメントをご覧いただくことになっており、大変心苦しく思っています。
このドキュメントを完成させるために、今後以下のような更新を予定しています。

| 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." | |
| Database files have to be updated before starting the server, here are the steps that had to be followed: | |
| # need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default | |
| brew unlink postgresql | |
| brew install [email protected] | |
| brew unlink [email protected] | |
| brew link postgresql |
