No se ha resuelto este problema, excepto algunas recomendaciones vagas sobre pg gem y postgres.

Tengo pg solo en producción en mi gemfile y sqlite3 para desarrollo:

end

#Nifty Scaffold

# Location - Geocoder

gem "mocha", :group => :test

Sin embargo, la aplicación sigue fallando (según los registros) y da un error de aplicación al mostrar el sitio. Todo funciona bien en el servidor local, por lo que definitivamente es un problema de implementación. ¿Alguien tiene alguna idea de lo que está yendo mal?

Muchas Gracias
