Re: ERROR: canceling query due to user request

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.

Regards
Iain
