a migração de toques falha do sqlite para o postgres rails4, ruby ​​1.9.3

Eu estou tentando migrar meu aplicativo Rails para Postgresql para heroku no entanto eu não posso obter toques para obter os dados do meu banco de dados SQLite3, aqui está o que eu tentei:

Crie o usuário do banco de dados Postgres para os novos bancos de dados

$ createuser f3
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) y

EDIT - Comando atualizado abaixo - use isso

$ createuser f3 -d -s

Crie os bancos de dados necessários

$ createdb -Of3 -Eutf8 f3_development
$ createdb -Of3 -Eutf8 f3_test

Atualize o Gemfile

gem 'sqlite3'
gem 'pg'
gem 'taps'
$ bundle

Atualizar database.yml

#development:
#  adapter: sqlite3
#  database: db/development.sqlite3
#  pool: 5
#  timeout: 5000

development:
  adapter: postgresql
  encoding: unicode
  database: f3_development
  pool: 5
  username: f3
  password:

#test:
#  adapter: sqlite3
#  database: db/test.sqlite3
#  pool: 5
#  timeout: 5000

test:
  adapter: postgresql
  encoding: unicode
  database: f3_test
  pool: 5
  username: f3
  password:

Inicie o servidor de toques no banco de dados sqlite

$ taps server sqlite://db/development.sqlite3 user password

Migrar os dados

$ taps pull postgres://f3@localhost/f3_development http://user:password@localhost:5000

Isso produz um erro:

MacBook-Pro:devise_example-master david$ taps pull postgres://david:abc123@localhost/f3_development http://user:password@localhost:5000
Receiving schema
Unable to fetch tables information from http://user:password@localhost:5000. Please check the server log.

Alguém tem uma correção para isso, (eu não posso simplesmente mudar para o Ruby 1.9.2 usando rvm, pois meu aplicativo usa muitas gemas que não estão funcionando para o antigo ruby).

E abaixo está o Log do servidor sqlite de toques quando o pull é emitido

MacBook-Pro:devise_example-master david$ taps server sqlite://db/development.sqlite3 user password
