不用意に brew upgradeしてしまった影響は、今だに出ているので、その対応を細々と。
元々入っていたPostgresのバージョンが9.6から10.1 にバージョンが上がった為、Postgresを起動しようとするとエラーで起動できなくなったので、その対応
$ postgres -D /usr/local/var/postgres 2018-01-22 14:18:16.340 JST [14935] FATAL: database files are incompatible with server 2018-01-22 14:18:16.340 JST [14935] DETAIL: The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.1.
brew の情報はとても親切なので、brew infoでpostgresの情報を出してやると、アップグレードコマンドも書いてあるので、そのとおりに実行。
$ brew info postgresql
postgresql: stable 10.1 (bottled), HEAD
Object-relational database system

postgres-xc (because postgresql and postgres-xc install the same binaries.)

==> Caveats
To migrate existing data from a previous major version of PostgreSQL run:
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
アップグレードコマンドを実行した結果、無事に

これで、成功していたら、postgresが起動しているので、後はいつもどおり、 ただ、結果のログを見ているとローカル接続以外は、できないよと警告が出ているので、hostを指定して接続している人は、 起動オプションなりpg_hba.confを変更しましょう
