Connecting to existing postgreSQL database in Win32

I’ve been runnning Perl under Apache for a while but have decided to try
using Ruby-on-Rails. My current database is postgreSQL 8.1. I have no
problem connecting to it using Perl or PHP 5. However, I’m obviously
missing something 'cos no matter what I do I cannot connect to the
database from RoR.
I have followed all of the instructions I could find and when I start
irb and type “require ‘postgres’” I get the value ‘true’ echoed back to
me.
My database is called bookkeeping and has several tables, one of which
is called ‘address’. I’ve changed the .yml file to have the following:

development:
adapter: postgresql
database: bookkeeping_dev
username: toby
password: whatever
host: localhost
schema_search_path: public

test:
adapter: postgresql
database: bookkeeping_test
username: toby
password: whatever
host: localhost
schema_search_path: public

production:
adapter: postgresql
database: bookkeeping
username: toby
password: whatever
host: localhost
schema_search_path: public

I’ve generated the app files by using the following commands:

rails bookkeeping
ruby script/generate model address
ruby script/generate controller address

When I try to start WEBrik I get the following response:

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application’s support team for more information.

Can anyone help before I decide that cutting my head off with a plastic
fork is more fun :slight_smile:

Many thanks
