Postgresql on FreeBSD

Hi there.

I came from linux and I'm not used to FreeBSD, so this might just be a
bsd question at all.

I installed the postgresql-7.0.2 port (make install), and then tried to
run the daemon, but it wouldn't. Finally, I got this error message:

Waiting for postmaster starting up..IpcMemoryCreate: shmget failed
(Permission denied) key=5432010, size=144, permission=700
This type of error is usually caused by an improper
shared memory or System V IPC semaphore configuration.
For more information, see the FAQ and platform-specific
FAQ's in the source directory pgsql/doc or on our
web site at http://www.postgresql.org.
IpcMemoryAttach: shmat failed (Permission denied) id=65536
FATAL 1: AttachSLockMemory: could not attach segment
..

I checked the kernel, and it's compiled with SYSV IPC.
Does anyone know what it is? Again, sorry if it's an out of topic
question.

Thanks in advance.
