Dear all, I have come to understand that postgresql needs sys v ipc. I haven't tried to figure out why exactly, but I'm sure they have good reasons. As I came to understand, if you enable jail_sysvipc_allow in rc.conf I am defeating the purpose of a jail. So basically I if you want pgsql in a jail you're wanting something which is impossible on FreeBSD. I got a suggestion that it might be possible to have sys v ipc confined to a jail instance and perhaps let it work like a telephone number. Every jail gets localized IPC numbers, and systemwide they just become jailid + localized ipc number. I was wondering if this is at all possible and if so how I would go about submitting a PR for this. Kind Regards, Gabor
