That's not going to work in plpgsql at the moment. Because it's "compiled", it 
has problems with things like this.

The usual answer is to use pltcl or some other more dynamic language.

In you particular example you could just build your execute statement as:... || my_column || ' AS foo FROM ' || ...

Then you can access the column as "foo"
