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?
