Ok, I got postgres to start... I used these settings.
kern.sysv.shmmax: 167772160 kern.sysv.shmmin: 1 kern.sysv.shmmni: 32 kern.sysv.shmseg: 8 kern.sysv.shmall: 65536 kern.sysv.semmni: 87381 kern.sysv.semmns: 87381 kern.sysv.semmnu: 87381 kern.sysv.semmsl: 87381 kern.sysv.semume: 10

I *think* the 10.3.7 upgrade broke my postgresql implementation...
I am getting this error at startup.
FATAL: could not create shared memory segment: Cannot allocate memory
DETAIL: Failed system call was shmget(key=5432001, size=10403840, 03600).
HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space. To reduce the request size (currently 10403840 bytes), reduce PostgreSQL's shared_buffers parameter (currently 1000) and/or its max_connections parameter (currently 100).
The PostgreSQL documentation contains more information about shared memory configuration.
The first time I noticed the problem I found that the shmmax was set low
at a bit more than 4MB ( perhaps the upgrade replaced /etc/rc ).
I increased the shmmax to about 64MB and still get the same error.
Here are the current kernel settings
kern.sysv.shmmax: 67108864 kern.sysv.shmmin: 1 kern.sysv.shmmni: 32 kern.sysv.shmseg: 8 kern.sysv.shmall: 1024 kern.sysv.semmni: 87381 kern.sysv.semmns: 87381 kern.sysv.semmnu: 87381 kern.sysv.semmsl: 87381 kern.sysv.semume: 10
Do I need to increase anything else?
I am on the digest, if someone knows the answer please CC to me also...
