+3)  How to increasing the number of semaphores.
+
+You may need to increase the number of sysv semaphores. By default,
+PostgreSQL allocates 32 semaphores, one for each backend connection. 
+This 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"

 Any other error is cause for suspicion.  In particular, if you see
