PostgreSQL BSDI BSD/OS port

Some corrections for the BSD/OS port. BSD/OS doesn't define
LC_MESSAGES, so that needs to be ifdef'd, and the kernel tuning
parameters are incomplete and suboptimal.

+You may need to increase the number of sysv semaphores.
+PostgreSQL 7 allowing the default number of backend connections
+allocates 32 semaphores, which is just over half the default system
+total of 60.
+
+The defaults are in /sys/sys/sem.h:
+
+/* Configuration parameters */
+#ifndef SEMMNI
+#define SEMMNI 10 /* # of semaphore identifiers */
+#endif
+#ifndef SEMMNS
+#define SEMMNS 60 /* # of semaphores in system */
+#endif
+#ifndef SEMUME
+#define SEMUME 10 /* max # of undo entries per process */
+#endif
+#ifndef SEMMNU
+#define SEMMNU 30 /* # of undo structures in system */
+#endif
+
+Set the values you want in your kernel config file, e.g.:
+
+options "SEMMNI=40"
+options "SEMMNS=240"
+options "SEMUME=40"
+options "SEMMNU=120"

Increase SHMMAXPGS by 1024 for every additional 4MB of shared
memory:

/sys/sys/shm.h:69:#define SHMMAXPGS 1024 /* max hardware pages...

The default setting of 1024 is for a maximum of 4MB of shared memory.
+PostgresSQL 7 allowing the default number of backend connections
+allocates about 1.2MB of shared memory.
+
+Enclose the above line with "#ifndef SHMMAXPGS" and "#endif", and in
+your kernel config file set the desired value, e.g.:
+
+options "SHMMAXPGS=8192"

For those running 4.1 or later, just recompile the kernel and reboot.
For those running earlier releases, there are more steps outlined below.
