SELinux has been distributed as a part of mainlined Linux 2.6.x
series for the recent five years. It can be enabled/disabled on
both of compile time and system bootup time, by user's preference.

SELinux is implemented as a security module on the LSM framework
which provides a set of neutral hooks for any other stuffs.
SE-PostgreSQL also had a similar stuff named as PGACE, but I agreed
an opinion that we (pgsql-hackers) don't want in-code framework two
months ago, so the PGACE has gone now.
