Putting memory pages to swap is the decision of the linux virtual memory
manager not postgres. If your db machine is swapping, first make sure
you have set sensible values for the ram related settings like
shared_buffers (25%), effective_cache_size (75%) and work_mem (keep it
modest at 4 to 16 MB).
