Built on 3.8.0-35-generic #50-Ubuntu SMP Tue Dec 3 01:25:33 UTC 2013 i686
i686 i686 GNU/Linux
Runs fine there.
Moved postgres install directory to 2.4.21-4.EL #1 Fri Oct 3 18:13:58 EDT
2003 i686 i686 i386 GNU/Linux
Not working fully there.
Note: It's says 2.4 kernel but I've been told that's misleading. The kernel
has upgrades that make it effectively 2.6.

I rebuilt with --enable-cassert, reran and no difference on 2.4 machine.
It's listening even on 2.4 machine. I ran strace on main postgres process
and got the following while running pg_isready.
Process 23811 attached - interrupt to quit
Process 23811 detached
But pg_isready just reports "/tmp:5432 - no response" after a few seconds.
