Would anything have to be written at all, save the CREATE AGGREGATE
suggested in the original message, using the existing array_cat as the
state transition function?
I suppose one might add an optimization to the existing array_cat to
detect the aggregate case, and realize it could clobber its left argument.
(But I'm not sure how much that would save, with arrays.)
