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.
Hmmm … once again this all just started magically working.
