I am a bit partial, with little deep thought, to the IMPORT mechanic. Changing them to actual session variables would be doable and you could allow for the IMPORT specification to use search_path or explicit means to locate said variables regardless of which schema they exist in. However, part of the goal is to blend into the broader database community and thus increase porting capabilities. I'm not sure how well this would help fulfill that goal. David J.
