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.

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
