OK, fine thanks to both.
I've found a page dealing with that prob :
Fixing the postgresql initdb fatal shared memory error on
Leopard<http://willbryant.net/software/mac_os_x/postgres_initdb_fatal_shared_memory_error_on_leopard>
The points are to :
Easy to fix; run:
sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216
(The first one's the critical one for me, but second seems appropriate too.)
This changes the limits in the currently-running kernel. To make these
values stick across reboots, add them to /etc/sysctl.conf, like this:
kern.sysv.shmall=65536
kern.sysv.shmmax=16777216
(Create this file if it doesn't already exist – it doesn't on fresh Leopard
installs.)
