+1)  To increase the amount of malloc'ed memory and files opened by
+PostgreSQL, add this:

+2a)  By default, only 4MB of shared memory is supported by BSDI. Keep in
+mind that shared memory is not pageable.  It is locked in RAM.
+
+To increase the number of buffers supported by the postmaseter, 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.
 
 For those running 4.1 or later, just recompile the kernel and reboot. 
-For those running earlier releases, there are more steps outlined below.
+For those running earlier releases, see step 2b.

-Use bpatch to find the sysptsize value for the current kernel. 
-This is computed dynamically at bootup.
+2b)  For 4.01 and earlier, use bpatch to find the sysptsize value for
+the current kernel.  This is computed dynamically at bootup.
 
 	$ bpatch -r sysptsize
 	0x9 = 9
