Right now adding up from ps the memory I have about 2GB.
Have an occassional program which uses up to 2GB.
Then I want to give some breathing room for when we have more connections so
that work_mem doesn't make the macihne hit swap.
At 32MB say worst case scenario I may have 50 operations using those 32MB,
that's about 1.5GB.
2+2+1.5 = 5.5
So I believe I have free about 2.5GB

So I will increase to 1.5GB then.
I may have more memory, but this is likely a safe value.
Thanks for the feedback.. Didn't even know about this setting.
