FATAL: huge pages not supported on this platform
<sigh> Nope, that didn't make any difference. Since I compile my own
binary,
I'm wondering if there's something that 'configure' didn't set properly.
A quick look at the PG source code says that that message means that
MAP_HUGETLB isn't defined. Our code is expecting <sys/mman.h> to provide
that symbol, which it should do by default according to what I can see on
my RHEL 6.6 box. Perhaps you've defined some of the feature restriction
macros like _POSIX_SOURCE?

Thanks for the helpful clue, Tom. I haven't knowingly defined
_POSIX_SOURCE or any other macros. I go through the same configure/make
process on the Centos 6.6 VM on my home PC, and huge pages works just
fine. Maybe it's an issue with CentOS 6.4?
