How to open more than 300 connections to postgres database.

["Nguyen, Lam Thuy" <l7nguyen(at)fcg(dot)com>]

Hello,
 
 I set max_connecion =300, but it only  allows upto 130 connections.
 
I tried to change some para in postgresql.conf file (shared_buffer...), but it was not efficient.
 
I read some document in postgres site said that i should change some para of System V IPC, but how do i change them ?
 
I am using WinXP, SP2, 4GB of GAM
 
 
Thanks for your help.
Lam
