学习oracle的同学都清楚,oracle的rman是最好的备份工具(一般第三方备份软件也基本上是通过调用rman的备份接口实现的)
pg_rman下载地址https://github.com/ossc-db/pg_rman/releases,下载和当前pg版本/操作系统版本对应的pg_rman包
安装pg_rman缺少包
缺少libpq.so.5()和postgresql10-libs相关的包
[root@localhost lib]# rpm -ivh /tmp/pg_rman-1.3.6-1.pg10.rhel7.x86_64.rpm
error: Failed dependencies:
libpq.so.5()(64bit) is needed by pg_rman-1.3.6-1.pg10.rhel7.x86_64
postgresql10-libs is needed by pg_rman-1.3.6-1.pg10.rhel7.x86_64
