Hi!

I resolved this problem. I have PostgreSQL 6.5.0 on sparc-sun-solaris2.6,
compiled by gcc 2.7.2.3. When I started postmaster -i, I had same error
messages.

You need to tune system parameter (shmsys) of kernel in /etc/system.

I add into /etc/system:

set shmsys:shminfo_shmmax=268435456
set shmsys:shminfo_shmmin=10
set shmsys:shminfo_shmmni=200
set shmsys:shminfo_shmseg=200
set semsys:seminfo_semmap=250
set semsys:seminfo_semmni=500
set semsys:seminfo_semmns=500
set semsys:seminfo_semmsl=500
set semsys:seminfo_semmnu=500
set semsys:seminfo_semume=100

then

# reboot -- -r

and

% sysdef

...

*
* IPC Shared Memory
*
 268435456      max shared memory segment size (SHMMAX)
    10  min shared memory segment size (SHMMIN)
   200  shared memory identifiers (SHMMNI)
   200  max attached shm segments per process (SHMSEG)
*

...

Now I start postmaster -i and it run ok.
