Tom Lane 810a8b1c80 Give up on running with NetBSD/OpenBSD's default semaphore settings. ... This reverts commit 38da053463, which attempted to preserve our ability to start with only 60 semaphores. Subsequent changes (particularly 55b454d0e) have put that idea pretty much permanently out of reach: people wishing to use Postgres v18 on OpenBSD or NetBSD will have no choice but to increase those platforms' default values of SEMMNI and SEMMNS. Hence, revert 38da05346's changes in SEMAS_PER_SET and the minimum tested value of max_connections. Adjust a comment from the subsequent patch 6d0154196, and tweak the wording in runtime.sgml to make it clear that changing SEMMNI/SEMMNS is no longer even a little bit optional on these platforms. Although 38da05346 was later back-patched into v17, leave that branch alone: it's still capable of starting with 60 semaphores, and there's no reason to break that.
