The pl/pgsql functions for the postgresql version of Bulk-mail are not
defined with the define_function_args function.
This breaks the package_instantiate_object proc that is called from
bulk_mail::new.
I tried to figure it out, but I just don't understand how to figure
out what the names of the args should be in that call to
define_function_args. Hopefully someone more familiar with bulk-mail
can take a look at it.
Thanks.
