Hi,
I have just installed the latest version of OS X panther (10.3.3) and
am now getting the following error message:
postgres$ /usr/local/pgsql/bin/postmaster -i -D /usr/local/pgsql/data
FATAL: could not create shared memory segment: Invalid argument
DETAIL: Failed system call was shmget(key=5432001, size=10444800,
03600).
HINT: This error usually means that PostgreSQL's request for a shared
memory segment exceeded your kernel's SHMMAX parameter. You can either
reduce the request size or reconfigure the kernel with larger SHMMAX.
To reduce the request size (currently 10444800 bytes), reduce
PostgreSQL's shared_buffers parameter (currently 1000) and/or its
max_connections parameter (currently 100).
If the request size is already small, it's possible that it is
less than your kernel's SHMMIN parameter, in which case raising the
request size or reconfiguring SHMMIN is called for.
The PostgreSQL documentation contains more information about
shared memory configuration.
Any ideas on how i can resolve this issue?
many thanks in advance

For start do:
sysctl -a | grep -i shm
or equivalent to find out your current kernel settings.
in FreeBSD the way to change shmmax is
# sysctl sysctl kern.ipc.shmmax=<some size>
I dont know about OSX tho..

Well, did you consider getting the value of SHMMAX?
Check with ulimit (as the postgres user).

You must edit the file /etc/rc ( sudo pico /ect/rc )
find the system tuning section and change as follows:
sysctl -w kern.sysv.shmmax=167772160
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=65536
warning... this change will not survive a system
update that updates the /etc/rc file.

I'am also getting this same problem with 10.3.3 Server. Worked fine
with 10.3.2.
kern.sysv.shmmax: 4194304
kern.sysv.shmmin: 1
kern.sysv.shmmni: 32
kern.sysv.shmseg: 8
kern.sysv.shmall: 1024
Those are the Values i get from the command posted. Have you figured
out a fix for this error?
Thanks.
