I have installed Postgres 8.2 in windows with default configuration.The windows machine has dual processor(2 GHZ,1GHZ) with 1 GB RAM.I use my java application with postgres and my database connection pool has some 25 connections.I understand from the documentation that postgres starts a seperate process for each of the connection.Now, my application and the database will be installed on the same system.Even under moderate load in my application, each of the postgres process occupies some 25 MB memory leading to total postgres memory usage of 500+ MB. Now, how do i limit the memory used by each of the postgres process to bring down the over all memory usage ?
