It's something we hope will be worked on for 8.4, but there are no firm
plans.
It's limited to 2Gb, actually, but *per process*. Since each backend is
it's own process, you can use way more than 2Gb RAM on a 64-bit system.
You can't use it for shared memory, but you can use it for local backend
memory (work_mem). But you'll need a lot of backends to do it, and you
will see other pieces of performance get worse with loads of backend.
Oh, and your RAM will still be used for disk cache, since that's managed
by the kernel.
