Yeah, you might've been able to get by with OpenBSD/NetBSD's default
semaphore settings before, but they really only let one postmaster
run at a time; and the TAP tests want to start more than one.
For me it seems to work to append this to /etc/sysctl.conf:

kern.seminfo.semmni=100
kern.seminfo.semmns=2000

and either reboot, or install those settings manually with sysctl.
