Answer 1

首先使用yum list postgresql91\\*查找此软件包，然后使用全名安装软件包

Answer 2

I have facing same issue when downloading postgres in linux. As i have followed some step from surfing some site. I have download repository RPM first and its downloaded successfully. then after in next step i have run below command

yum install postgresql10-server postgresql10

then getting below error

No package postgresql10-server available. No package postgresql10 available.

in resolution of that i have run yum list command. and you can find out list of available software where postgres also mentioned so used specific name of postgres in command like

sudo yum install postgresql-server.x86_64

And it is working fine.
