使用oracle goldengate同步postgresql到postgresql

在之前的文档中，有测试验证postgresql到oracle的同步。如果想了解更多，请参考连接：
https://blog.csdn.net/bing_yuan/article/details/129613238?sharetype=blogdetail&sharerId=129613238&sharerefer=PC&sharesource=bing_yuan&spm=1011.2480.3001.8118

在这篇文章中将测试验证从postgresql到postgresql的同步，同步工具使用的是oracle goldengate（OGG）。

测试环境：
ogg 21.3
postgresql 9.4.1
目标端postgresql 12.14

测试的同步是从postgresql的备库同步数据到目标库
|192.168.56.11 |pg主库
|192.168.56.12 |pg只读备库
|192.168.56.101 |pg目标库 ogg端

软件的安装过程在这篇文章中忽略，具体请参考上面的链接。

以下是具体的的测试过程

尝试更换OGG版本，ogg从21.3版本才开始有postgresql版本。目前出了一个最新的版本23.4.
