Re: createdb script bug in 7.3RC2?

As a follow-up I get an error when dropping plpgsql and then trying to
re-create it ...

$ psql JC -c "drop language plpgsql cascade"
NOTICE:  Drop cascades to function cancell_all_li()
NOTICE:  Drop cascades to trigger insert_invoices on table invoices
NOTICE:  Drop cascades to function update_invoice_price()
NOTICE:  Drop cascades to trigger update_invoice_li_price on table
invoice_li
NOTICE:  Drop cascades to function max(date,date,date)
DROP LANGUAGE
$ createlang plpgsql JC
ERROR:  function plpgsql_call_handler already exists with same argument
types
createlang: language installation failed

Once a language is dropped I should be able to re-add it no? Or isn't
dropping it enough?
