I have downloaded PostgreSQL but it will not install. It downloads a disc image and when I launch the application it asks me for my password, briefly flashes a startup banner and then stops responding. The ReadMe says this: PostgreSQL One Click Installer README
Shared Memory
PostgreSQL uses shared memory extensively for caching and inter-process
communication. Unfortunately, the default configuration of Mac OS X does
not allow suitable amounts of shared memory to be created to run the
database server.
Before running the installation, please ensure that your system is
configured to allow the use of larger amounts of shared memory. Note that
this does not ‘reserve’ any memory so it is safe to configure much higher
values than you might initially need. You can do this by editting the
file /etc/sysctl.conf - e.g.
% sudo vi /etc/sysctl.conf
On a MacBook Pro with 2GB of RAM, the author’s sysctl.conf contains:
kern.sysv.shmmax=1610612736
kern.sysv.shmall=393216
kern.sysv.shmmin=1
kern.sysv.shmmni=32
kern.sysv.shmseg=8
kern.maxprocperuid=512
kern.maxproc=2048
Note that (kern.sysv.shmall * 4096) should be greater than or equal to
kern.sysv.shmmax. kern.sysv.shmmax must also be a multiple of 4096.
Once you have edited (or created) the file, reboot before continuing with
the installation. If you wish to check the settings currently being used by
the kernel, you can use the sysctl utility:
% sysctl -a
The database server can now be installed.

If I need to do anything with files then I have no idea what to do, could anyone help or direct me to a proper download link etc?
