    I recently installed Perfsonar tool kit via "yum install perfsonar
    tool-kit" on centos 7 and seeing errors on screen related to
    Pscheduler and Postgres. I also see psheduler status as not running on
    web gui. I have not seen this before so this might be happening with
    new release or something. Please advise. Thanks.

The problem appears to be here:
    
      Installing : python3-psycopg2-2.8.5-1.rhel7.x86_64

The pScheduler RPMs call for a package that provides python-psycopg2 which, 
on a CentOS 7 system, should be  provided by python2-psycopg2.  Your system 
may have additional YUM repositories configured; if the python3-psycopg2 is 
reporting itself as the provider for python-psycopg2, it's doing so in error. 
 Running "yum whatprovides python-psycopg2" should give you a hint about what 
repo is providing it.  On a CentOS 7 system installed according to the 
directions, the packages should be provided by the base and perfSONAR 
repositories.

I'm unable to reproduce the problem on a minimal CentOS 7 (the Vagrant 
centos/7 box) with these steps from the installation instructions:

    yum -y install epel-release
    yum -y install 
http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/perfSONAR-repo-0.9-1.noarch.rpm
    yum -y clean all
    yum -y install perfsonar-toolkit
