Correct. The only real adjustable limit is the size of the Windows pagefile, but that one is normally dynamic. But
theremust be room for all the shared memory in it. It's not going to be there, but the space is reserved.
That said, if you need to increase the pagefile size to accomodate your shared buffers, you likely have way too large
valuefor shared buffers.
