"Permission denied" seems like an odd error for a request to create
a shared-memory segment. The only likely thing I can think of is
if there is already a shmem segment with that same key belonging to
another user --- perhaps left over from a previous run of the postmaster
under a different userID? Anyway, use "ipcs -a" to see what's hanging
around your system. "ipcrm" (or our ipcclean script) can be used to
get rid of unwanted segments.
