Wont install on Oracle7/CentOS - PGSQL issue?

Wont install on Oracle7/CentOS - PGSQL issue?

We currently have v11300 Essential edition running without issue on Suse Enterprise 11 SP3. I need to have this installed on Oracle 7 as we are migrating away from Suse. The latest version downloadble installs and runs fine, except it no longer supports ESXi, only vCenter which we do not use.We have OpManager to monitor 3 ESXi servers, so upgrading to the new version is a non-issue right now

So far I have not been able get OpManager install successfully on either Oracle 7 or CentOS 7. So far the problems seems to be first and foremost with PGSQL which does not load. I have gone through the archive installing older versions in an attempt to get a successful install and upgrade incrementally. The only version I can get install is 9200 which if need be, we will have to use. However I would prefer to have 11300 running on new Oracle7. 

Closest I do get to install, when I start with StartOpManagerServer.sh, it gets to "Created table PROTOCOLDETAILS" and just hangs. Opening another console I see these process:
3687 pts/0    Sl+    0:15 /opt/ManageEngine/OpManager/jre/bin/java -cp ................
 93727 ?        S      0:00 /opt/ManageEngine/OpManager/pgsql/bin/postgres -D................ 
 93728 ?        Ss     0:00 postgres: logger process   
 93730 ?        Ss     0:00 postgres: checkpointer process   
 93731 ?        Ss     0:00 postgres: writer process   
 93732 ?        Ss     0:00 postgres: wal writer process   
 93733 ?        Ss     0:00 postgres: autovacuum launcher process   
 93734 ?        Ss     0:00 postgres: stats collector process   
 93760 ?        Ss     0:00 postgres: postgres OpManagerDB 127.0.0.1(55117) idle
Last process is repeated about 40 different times.

Next time I attempt to start OpManager, it gets to "inside addon check" and then nothing. This occurs on multiple installs of O7 or CentOS, regardless of OpManager versions above 9200 to latest.
