Yes. 2*max connection is minimum. Anything additional is always welcome as long
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
allow for indexing. Default is 4 MB. I would something like 32MB should help a
lot..
