I've compiled and installed PG 9.4.0 on my Linux VM, but attempts to
enable huge pages (huge_pages=on in postgresql.conf) have resulted in
this error message in the log:

   FATAL:  huge pages not supported on this platform

I'm running CentOS 6.4.  Here's the uname output:

   Linux 2.6.32-358.2.1.el6.x86_64 #1 SMP Wed Mar 13 00:26:49 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux

I've set a reasonable nr_hugepages value in /etc/sysctl.conf.  Is there
some kernel mod or environment variable that I also need?
