So I see this patch added 32 PGPROCs and hence 32 semaphores to the system's requirements. Unsurprisingly, this broke OpenBSD/NetBSD again: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=sawshark&dt=2025-03-18%2016%3A20%3A05 It's probably time to just abandon the idea of being able to run with only 60 semaphores. I wonder though if we ought to revert 38da05346 and/or 6d0154196 in view of that. regards, tom lane
