Systemd stdout doesn't handle this and probably never will. Check your 
logs, as with any service issue.

I hope you realize that all your previous SQL data is in the old 
/var/lib/pgsql/data directory.

PostgreSQL version upgrades have always had to be handled by data dumps 
and data imports. With PostgreSQL 9.0 an upgrade utility was created, 
but it is not run by default as it is not considered stable. It works 
fine for me though. Perform a "yum install postgresql-upgrade" to 
install the utility and run "pg_upgrade" as root.

I suggest that you study PostgreSQL administration. I don't have a 
problem with how the current system works.
