Yeah (didn't think about SQL ones).  Although the deferred 
creation with like a nulled out prosrc would probably solve 
these problems as long as you never wanted to actually 
call the function until the restore was done, so we wouldn't
want any default values, rules or triggers that might use them
to be activated.
