The two key parameters that can help speed up your index creation time
are shared_buffers and most importantly maintenance_work_mem. Also,
maintaining a lean, non-bloated table helps speeding up your index
creation time as well since it'll take less time to scan through a
table. 
 
For more info on the parameters I think the documentation is pretty
clear which can be found at:
http://www.postgresql.org/docs/8.2/static/runtime-config-resource.html
There's also a pretty nice doc by Josh Berkus that can be found at
http://firstdba.googlepages.com/PostgreSQL.conf_80.pdf

Hi,

I am new to postgresql and trying to figure out postgres.config file.
There are few variables that I need an understanding about. 

shared_buffers,
temp_buffers,
work_mem
maintenance_work_mem

Can anyone please explain when and how these are used? I am trying to
understand the importance of these 4 while creating an index on a table.
Any help will be appreciated.

Thanks,
Shreya
