I'm going to second Neil here. This feature becomes useful *only* when there
is a certified or de-facto universal standard XML representation for database
data. Then I could see a case for it. But there isn't.
We've done it in phpPgAdmin (we made up our own standard), and a couple
of people use it. I also do not think that it should be in the backend
until there is a standard. Here is what phpPgAdmin produces (note NULL
handling):
