Comment(by robe):

 Yah those I took care of to some extent, but AGGREGATES don't seem to
 support default args fully (you can't define a default arg withint a
 CREATE AGGREGATE nad the state functions it doesn't seem to want to use
 one with a default arg that would otherwise match what it needs), so you
 would end up with more than you normally would with a regular function.
