Probably SELinux is set up to deny random connections originating from the
postgresql daemon. If disabling SELinux makes the problem go away then
that's it. (I do *not* recommend that as a permanent solution, of course.
You'll want to find some finer-grained change to the security policy.
Don't remember enough about SELinux to know what the most likely bet is.)
