Large Database & Indexes (Indices?)

From

I am constructing a large ( by some standards) database where the largest table
threatens to be about 6-10 Gb on a Linux system. I understand that postgresql
splits the tables into manageable chunks & I have no problem with that as a
workround for the 2 GB fs limit
..     My question concerns the indexes ,the first of which looks to be  around
40 % of the table size. How is this
handled and how do I create subsequent indices on large tables given that I
can't interrupt the process,  move and symbolically link chunks ?

IIRC Indices you the same storage manager as tables, so they should split
at the same intervals as tables (default is 1Gb). Someone correct me if
I'm wrong.
