ーーーーーここまでーーーーー
上あたりの行にpython３.６.７にアップデートしろみたいなことが書かれているのでそれが問題なのでしょうか？何が良くないのかよく分かりません。どなたか教えていただけると嬉しいです。

Answer 1

pythonのバージョンに関しては「セキュリティアップデート来たから更新した方が良いよ」というメッセージなので、エラーとは直接関係ありません（更新するにこしたことはないんでしょうが）。

直接のエラー原因は

Error: could not determine PostgreSQL version from '10.6'

です。これで検索するといろいろ出てくるのでそれを参考に対処してみてください。
