I can't do any benchmarks because I keep getting errors. But I have dropped
this value down and I am not getting the out of memory errors any more. I
was trying to solve other problems by bumping this way up but it seemed to
just cause more problems. I found several things in documentation that says
that bumping the shared_buffers\work_mem up to over 1gb was fine. Is that
strictly for linux boxes?
