-    3.2) When I start postmaster, I get a Bad System Call or core dumped
-    message. Why?
-    
-   It could be a variety of problems, but first check to see that you
-   have System V extensions installed in your kernel. PostgreSQL requires
-   kernel support for shared memory and semaphores.
-   
-    3.3) When I try to start postmaster, I get IpcMemoryCreate errors. Why?
-    
-   You either do not have shared memory configured properly in your
-   kernel or you need to enlarge the shared memory available in the
-   kernel. The exact amount you need depends on your architecture and how
-   many buffers and backend processes you configure for postmaster. For
-   most systems, with default numbers of buffers and processes, you need
-   a minimum of ~1 MB. See the PostgreSQL Administrator's Guide/Server
-   Run-time Environment/Managing Kernel Resources section for more
-   detailed information about shared memory and semaphores.
-   
-    3.4) When I try to start postmaster, I get IpcSemaphoreCreate errors. Why?
-    
-   If the error message is IpcSemaphoreCreate: semget failed (No space
-   left on device) then your kernel is not configured with enough
-   semaphores. Postgres needs one semaphore per potential backend
-   process. A temporary solution is to start postmaster with a smaller
-   limit on the number of backend processes. Use -N with a parameter less
-   than the default of 32. A more permanent solution is to increase your
-   kernel's SEMMNS and SEMMNI parameters.
-   
-   Inoperative semaphores can also cause crashes during heavy database
-   access.
-   
-   If the error message is something else, you might not have semaphore
-   support configured in your kernel at all. See the PostgreSQL
-   Administrator's Guide for more detailed information about shared
-   memory and semaphores.
