I've been reading this thread with interest, may I ask a few additional 
questions ? 

- What version of postgresql are you running, compiled from tarball source or 
RPM version ? 
- Is there any good reason to still run this server on a RedHat 6.2 (non 
supported platform from RedHat) ? 
- How large are your databases, and how much usage do you have ? 
- What kinds of API's do you use to interface ? 
- Is the application running locally or do you use IP connections remotely ?

Reason I am asking is that I still have never had postgresql go bad like 
that.. I can always stop it properly, and to this date have had very few 
problems with postgresql itself. I am interested in your problems because I'd 
like to be aware of issues I can eventually run into.. (Better care before 
than later ? :-)

My own configuration is like this : 

- Postgresql 7.1.3 with OpenFTS, both compiled from source tarballs
- Debian Linux 2.2.x platform
- PHP and Perl applications accessing postgresql from remote machines via IP
- Not very large databases (100s of MBs) but very frequent read, and quite 
frequent insert / update activity

For the record, server uptime now is equal to the last time I rebooted for a 
kernel recompilation, and during that time I have been forced to restart 
postgresql only because of hangups on the Application servers (apache w. php 
/ perl) ..
