Tom Lane a2b22d8e80 Doc: update our docs about kernel IPC parameters on *BSD. runtime.sgml said that you couldn't change SysV IPC parameters on OpenBSD except by rebuilding the kernel. That's definitely wrong in OpenBSD 6.x, and excavation in their man pages says it changed in OpenBSD 3.3. Update NetBSD and OpenBSD sections to recommend adjustment of the SEMMNI and SEMMNS settings, which are painfully small by default on those platforms. (The discussion thread contemplated recommending that people select POSIX semaphores instead, but the performance consequences of that aren't really clear, so I'll refrain.) Remove pointless discussion of SEMMNU and SEMMAP from the FreeBSD section. Minor other wordsmithing. Discussion: https://postgr.es/m/27582.1546928073@sss.pgh.pa.us	7 years ago

Tom Lane a2b22d8e80 Doc: update our docs about kernel IPC parameters on *BSD.

runtime.sgml said that you couldn't change SysV IPC parameters on OpenBSD
except by rebuilding the kernel.  That's definitely wrong in OpenBSD 6.x,
and excavation in their man pages says it changed in OpenBSD 3.3.

Update NetBSD and OpenBSD sections to recommend adjustment of the SEMMNI
and SEMMNS settings, which are painfully small by default on those
platforms.  (The discussion thread contemplated recommending that
people select POSIX semaphores instead, but the performance consequences
of that aren't really clear, so I'll refrain.)

Remove pointless discussion of SEMMNU and SEMMAP from the FreeBSD
section.  Minor other wordsmithing.
