Hi Scott,
its been a while since you posted this email, just wondering if you ever did get resolution on the issue ? there has been a recent updated for pgsql in dev.centos.org - can you update to the latest and see if this error is reproduceable ?
I believe this stemmed from the fact that the original run of the compat-libs only contained the x86 binaries, and not the x86_64 ones. This should have been fixed with the second build, but if it hasn't, I'd like to know about it. One of these days I'll get myself an opteron box where I can do some proper builds.
