I tried to give this a test drive today but got stuck. I got sepgsql
compiled OK, but look what happens when I try to start the server:

[rhaas(at)f15selinux ~]$ postgres
FATAL: could not load library
"/home/rhaas/project/lib/postgresql/sepgsql.so":
/home/rhaas/project/lib/postgresql/sepgsql.so: undefined symbol:
getpeercon_raw

This is Fedora 15, with all available updates applied.
