You'd need to read up on Red Hat's "SCL" packaging system to understand
how to use that rh-postgresql95 package.  SCL is since my time there,
but I'm pretty sure it's intentional that it's not in the default PATH.

But TBH, all the versions available from Red Hat for RHEL7/CentOS7 are
out of support as far as the upstream community is concerned; to us it's
pretty mystifying why you'd be trying to migrate to an already-years-dead
release branch.  I'd suggest getting some more modern release from
https://www.postgresql.org/download/
