oracle goldengate实现postgresql 到 postgresql的实时同步
源端：postgresql1 -> postgresql2 流复制主备同步
目标端：postgresql
数据库版本：postgresql 12.14
ogg版本：21.3
数据库安装以及流复制主备同步配置忽略。以下直接进入OGG的配置
odbc配置：
[root@oradb1 ogg213]# yum list |grep postgresql-odbc.x86_64
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
