Unsurprisingly, this has completely broken buildfarm member sawshark:
you added 13 new semaphores to the system's default requirements,
and we only had headroom for about 4 (cf. 38da05346).
Now maybe we should just abandon the notion that we ought to be
able to start up under OpenBSD/NetBSD's tiny default value of SEMMNS.
If so I'd be inclined to go revert 38da05346, at least in HEAD.
But I kind of wonder whether this feature actually brings value
commensurate with causing installation problems on real-world OSes.
regards, tom lane
