I have tested my solution a bit more and I have to say that reusing a
semaphore by a new backend works OK. But it is not possible for a newly
created backend to use a semaphore allocated by postmaster (it freezes on
test if the semaphore with given key already exists - done with
semId=semget(semKey, 0, 0) in function IpcSemaphoreCreate() in
storage/ipc/ipc.c ). Why it is, I don't know, but it seems that my solution
uses the ipc library in the right way. There are no longer any error
messages from the ipc library when running the server. And I can't say that
the ipc library is a 100% correct implementation of SysV IPC, it is probably
(sure ;-) )caused by the Windows internals.
