I'm so confused.  :-)

OK, so all functions can be upgraded to version 1 calling sequence, not
just ones used for triggers.  I think I have it but the docs could still
use some work.  If someone wants to check out the latest version of my
chkpass function in contrib and let me know if I seem to have the right
idea now then I will go ahead and try to improve the docs.
