Thread: Large Database & Indexes (Indices?)
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.

Forget my last posting - sorry - I'm being stupid .fs size is, of course 4 Tb
