Thanks for fixing this. I wasted a few hours trying to deploy a simple Sinatra app to Heroku that refused to connect to the shared database.

I kept getting this error but couldn't figure out why:
ActiveRecord::StatementInvalid: PGError: ERROR: invalid value for parameter "client_min_messages": ""

Since I wasn't setting a value for :min_messages, it was being set to "", and hence the error.
