Como exportar um despejo Postgres compatível com Heroku do Ninefold?

Estou tentando migrar meu banco de dados postgres de nove vezes para heroku.

O comando que estou usando para exportar é:

PGPASSWORD=password pg_dump -h ipaddress -p port -U user -d database -Fc --no-acl --no-owner -x -O -N postgis > ninefold-backup.dump

Em seguida, faça o upload para o S3 e execute este comando:

heroku pg:backups restore 'https://s3-us-west-2.amazonaws.com/bucket/ninefold-backup.dump' DATABASE_URL -a app --confirm app

Então heroku relata:

An error occurred and your backup did not finish.

Please run `heroku pg:backups info r003` for details.

Nos logs mostra erros como estes:

2015-05-23 22:32:36 +0000: pg_restore: creating COMMENT EXTENSION xml2

o que estou perdendo?

Encontrou uma maneira. Parecia haver algum problema com as extensões que Ninefold estava usando, portanto, ao adicionar uma -n publicopção, ele criaria o backup apenas do esquema público.

PGPASSWORD=password pg_dump -h ipaddress -p port -U user -d database -Fc --no-acl --no-owner -x -O -N postgis -n public > ninefold-backup.dump
