尝试使用heroku pgbackups -tool恢复数据库备份。
我通过公开网址下载备份:
$ heroku pgbackups:url 'backup-name'
创建数据库:
$ createdb 'dbname' -U postgres
并尝试从* .dump文件恢复:
$ psql -U postgres -d 'dbname' -f *.dump
我最终遇到了以下类型的语法错误:
ERROR: syntax error at or near "PGDMP"
...
ERROR: invalid byte sequence for encoding "UTF8": 0x9d
HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding"
好的,所以这与编码有关 - 但是我如何解决呢?
config / application.rb和我的postgres服务器都将编码设置为UTF-8。 database.yml配置了sqlite(尚未涉及生产配置)。 Gemfile只是:
gem 'pg'
答案 0 :(得分:53)
我找到了答案directly from the manual:
$ curl -o latest.dump `heroku pgbackups:url`
$ pg_restore --verbose --clean --no-acl --no-owner -h myhost -U myuser -d mydb latest.dump
