as it does not starve the system.
If you have a gig of memory and shared buffers are 536MB as you have indicated,
who is taking rest of the RAM?
What are your current settings? Could you please repost. I lost earlier

500-600MB would take you comfortably in this case..

That actually depends upons size of table you are indexing and time you can

lot..
