转换为PostgreSQL后备份还原时出错

我正在使用以下指南将Gitlab服务器迁移到Omnibus版本：

在备份还原的rake脚本中，我在backticks中发现了几个语法错误

@GitLabVM:~$ sudo gitlab-rake gitlab:backup:restore BACKUP=1452260428
Unpacking backup ... done
Restoring database ...

LINE 1: UNLOCK TABLES;
        ^

LINE 1: DROP TABLE IF EXISTS `audit_events`;

我已经检查了sql文件，它没有我收到错误的背景标记

DROP TABLE IF EXISTS "abuse_reports";

Gitlab中有一个相关的bug报告，但它已被弃用，我似乎无法找到这个bug发生的地方。如果您能帮我找到这件事，我将不胜感激。多谢各位

这通常发生在从MySQL数据库创建转储时，以及在恢复过程中Postgress db收到这些语法错误时

您可以创建一个与PostgreSQL兼容的单独数据库转储，只需执行以下步骤即可

sudo -u git -H mysqldump --compatible=postgresql--default-character-set=utf8 -r gitlabhq_production.mysql -u root gitlabhq_production -p

# Clone the database converter
sudo -u git -H git clone https://github.com/gitlabhq/mysql-postgresql-converter.git -b gitlab

# Convert gitlabhq_production.mysql
sudo -u git -H mkdir db
sudo -u git -H python mysql-postgresql-converter/db_converter.py gitlabhq_production.mysql db/database.sql
sudo -u git -H ed -s db/database.sql < mysql-postgresql-converter/move_drop_indexes.ed

# Compress database backup
# Warning: If you have Gitlab 7.12.0 or older skip this step and import the database.sql directly into the backup with:
# sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql
# The compressed databasedump is not supported at 7.12.0 and older.
sudo -u git -H gzip db/database.sql

# Replace the MySQL dump in TIMESTAMP_gitlab_backup.tar.

# Warning: if you forget to replace TIMESTAMP below, tar will create a new file
# 'TIMESTAMP_gitlab_backup.tar' without giving an error.

sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql.gz

# Done! TIMESTAMP_gitlab_backup.tar can now be restored into a Postgres GitLab
# installation.
# See https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/raketasks/backup_restore.md for more information about backups.
