Hi Tom, I agree with your assessment of this. I'm no expert on Linux, and I'm new to Postgres but I'm learning. I hope to have a chance to play with and test these kinds of configuration settings before the system goes live. Unfortunately there is no plan for a test environment that is comparable to the production environment. By the way, I've been using 7.4 for a little while now (in development) and my feeling is that the DB has matured considerably since the previous version I used which was 7.1. It's looking good so far.
