Hi hackers,
The manual implies that only Linux can use huge pages. That is not
true: FreeBSD, Illumos and probably others support larger page sizes
using transparent page coalescing algorithms. On my FreeBSD box
procstat -v often shows PostgreSQL shared buffers in "S"-flagged
memory. I think we should adjust the manual to make clear that it's
the *explicit request for huge pages* that is supported only on Linux
(and hopefully soon Windows). Am I being too pedantic?
