Ugh. I don't recall exactly when Apple got around to including ipcs, but I guess it wasn't in 10.3.9. Your problem is that you're flying blind because you cannot tell what's going on in shared memory. What I suspect is that there's an unused shared memory segment sitting there (perhaps left over from a failed initdb) and eating a sufficiently large fraction of SHMALL that there's no room for another. If correct, then rebooting should make it go away and let you initdb. Since you haven't got ipcrm either, there's basically no other way to get rid of an unwanted shmem segment :-( You should think about upgrading to 10.4.x btw --- for Postgres admin purposes, having ipcs and ipcrm available is alone worth the price of admission. And it does seem they've improved the OS's performance in various ways too. regards, tom lane
