Hello
The default number of semaphores sets of NetBSD ist too low for Postgres
(tested on 9.1)
I would suggest replacing the sentence:
In NetBSD 5.0 and later, IPC parameters can be adjusted using sysctl,
for example:
$ sysctl -w kern.ipc.shmmax=16777216
with the following:
The default settings are only suitable for small installations. In
NetBSD 5.0 and later, IPC parameters should be adjusted using sysctl,
for example:
$ sysctl -w kern.ipc.shmmax=16777216
$ sysctl -w kern.ipc.semmni=256
$ sysctl -w kern.ipc.semmns=512
