Re: semctl(): Invalid argument

FWIW, i've been running two postmasters on the same port on a
FreeBSD 6.0-RELENG server, one in the host and one in a jail (this
is on a devel server). I don't like running postgresql in a jail
anyway, because it involves enabling sysv IPC inside jails, which
sort of defeats the entire purpose of having a jail..

Gr,

Koen
