Heroku db连接错误：使用PostgreSQL推送

Question

I have suddenly started seeing this strange error when trying to push my database to heroku.

> heroku db:push
Auto-detected local database: postgres://infinity:infinity@localhost/infinity_development?encoding=utf8
Failed to connect to database:
Sequel::DatabaseConnectionError -> TypeError wrong argument type String (expected Array)

My app works fine - the credentials are all set locally.
