Jim,
I appreciate the time invested in your reply and explanation. Although I still don't grasp the concept as well as I'd like, you did help me identify the issue and get it resolved. I've determined that I indeed have/had two versions of PostgreSQL installed on the system. I had originally installed it during the RH9 install, but later "thought" I removed it and then reinstalled using the provided step-by-step instructions.
After I figured this out, it was considerably easier in getting the system functional. In fact, I have a fully installed system waiting for me to begin testing on now, woohoo 😉
The only issue I'm having still is getting the auto-restart for AOLServer working correctly, specifically in attempting to get the inittab portion working (the restart-aolserver script works fine). I'm still trying some things though, but might ask for assistance if our UNIX admin is too busy this week. Thanks again for your help!
