Hi Tom,

Firstly I'd just like to say I am really impressed by the phenomenal
response time from posting the email to receiving a patch - absolutely
fantastic, especially on a Sunday! I've built up a new RPM to test the
patch and the test case from the email works brilliantly now. We'll
probably start tagging more data from large tables on our live system
over next weekend which will give me a chance to give it a through
testing, but as the email test case works I'm really confident that
you've managed to nail this one!

Once again, thank you very much,

Mark.
