I just downloaded and installed RC3 on my OS X system (10.3.7), and I'm
getting a shared memory error when trying to run initdb (error message
listed below). I received a similar error a few weeks ago after
upgrading my OS to 10.3.7, but I was able to get around that by
reducing the shared_buffers setting in postgresql.conf. I'm not sure
how to work around this one, though, since I'm starting from scratch
and the error is coming from initdb. What is the best way to correct
this situation?
Any help would be appreciated!
Thanks,
Tim

DETAIL: Failed system call was shmget(key=1, size=1155072, 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 1155072 bytes), reduce PostgreSQL's
shared_buffers parameter (currently 50) and/or its max_connections
parameter (currently 10).
The PostgreSQL documentation contains more information about
shared memory configuration.
