我在使用 Docker 运行 Ruby on Rails 项目时遇到问题。我有预感这与运行 macOS Catalina (10.15.1) 有关。当我尝试这样做时，问题就出现了docker-compose run web rake db:create。
当我运行时，docker-compose run web rake db:create我得到以下输出：
Starting vft_db_1 ... done
PG::InvalidParameterValue: ERROR: invalid value for parameter "client_min_messages": "panic"
HINT: Available values: debug5, debug4, debug3, debug2, debug1, log, notice, warning, error.

host: db
