You can't do it nohow in plpgsql. I believe it's relatively simple in
pltcl or plperl, though, because those languages don't try to precompile
column references.
Or if you're feeling bold, you could write the trigger in C ;-).
There are some examples that do pretty similar stuff in contrib/spi/.
If performance is a big concern this would be a good plan anyway.
