Thanks Steve, the draft looks good.  From a user side, these added 
operators and functions will be very useful (such as the powerful LIKE 
command, and the TEXT formatting options).  I think 99% of the users 
would be fine with these changes even if there is a slight performance hit.

Feedback on the RFC: for the final RFC version I'd like to see all of 
the new operators and functions listed.
