Pg on win32 is 32-bit. It has a total address space of 2Gb, minus the OS
overhead, minus the code, minus local memory etc. You're just not going
to fit that much in the address space.
There are fixes to reduce the memory usage of the postmaster (which is
likely what runs out first, unless you have a large work_mem) in 8.3,
but you're still right up against the wall with that large
shared_buffers. Plus, as I said in my other email, you're likely not
seeing any performance gain from such a large shared_buffers anyway. If
you are, you're seeing something new, and we definitely need to find out
why.
