I wish I could write portable code, if possible:-)

I'm basically writing views on top of the information_schema under the 
assumption that what is expected to be a key is a key. The information 
schema is *useless* otherwise as wrong tuples are built on join, and 
derived information is not reliable.

I guess I must the only actual user of the information_schema, and it will 
soon be back to zero user, which will be fine from the developers point of 
view.
