我正在尝试将 PostgreSQL 转储从 heroku 导入本地数据库（以模拟本地环境中的生产数据）。我在 OSX 上本地使用 postgres 9.2。以下是我在控制台中采取的步骤：

dropdb db_dev

createdb db_dev

heroku pgbackups:capture HEROKU_POSTGRESQL_MAROON_URL

curl -o latest.dump `heroku pgbackups:url`

pg_restore --verbose --clean --no-acl --no-owner -h localhost -U connorwarnock -d db-dev latest.dump

以及随后的错误：

pg_restore: connecting to database for restore
pg_restore: dropping COMMENT EXTENSION plpgsql
pg_restore: dropping EXTENSION plpgsql
pg_restore: dropping COMMENT SCHEMA public
pg_restore: dropping SCHEMA public
pg_restore: [archiver (db)] Error while PROCESSING TOC:

没有数据被导入。似乎公共架构引起了问题（我已经手动删除了架构并再次尝试，但无济于事）。也许 hstore 扩展正在引起麻烦？关于如何避免这些错误的任何其他想法？

看起来您template1包含hstore扩展名和可能的其他更改。

我建议从包含基本默认数据库的只读模板中删除db_dev并重新创建它。template0

createdb -T template0 dev_db

如果这不起作用，请在此处发布更新的错误并发表评论。
