This is what happens if you try and use a postgresql.conf with
parameters set for a 64-bit installation on a 32-bit operating system.
You're trying to do this:
shared_buffers = 7680MB
But the 32-bit Centos 5.2 you're using doesn't allow you to allocate
more than 2GB of RAM for that. If there really is around 32GB of RAM in
there, like I'm assuming the 5.4 system has for pgtune to made this
suggestion, you certainly will need to install a 64-it OS on it to take
advantage of that usefully.
