Can't duplicate it here.  Can you attach to the postmaster process with
a debugger and see what it thinks its state is?  The static variables in
postmaster.c are the things to look at.  Are there still entries
in BackendList?  Are any of StartupPID, ShutdownPID, CheckPointPID
nonzero?  What's the value of Shutdown?  Etc.
