A ramdisk for Vista with "unlimited space"

A ramdisk for Vista with "unlimited space" I am using PostgreSQL and I want to explicitly place a database with 4 gb of data in memory. I have read a lot of forums discussing whether this is a good idea and I have decided that I want to give it a try. I am using a Vista machine. I currently have only 2 gb of ram.

"Part of your problem may not be so much that it won't swap. If I remember correctly, the 4 GB address space is split in half on Vista 32-bit (which I assume you're using from the behaviour specified), so each application has 2 GB and the kernel and drivers have the other 2 GB.

That means it's probably not possible (without workarounds) to get more than 2 GB into a ramdisk on Vista 32-bit. On 64-bit you would have far more space and be restricted only to how much swap you had available.

Have a look here."
