There are a couple of issues. One is that we probably don't want two
pg_type entries for every single table. Will you be satisfied if only
CREATE TYPE AS ... makes an array type? The other is that, at least at
the time they were written, the array support routines couldn't handle
composite array values. Things might or might not be easier today;
I don't think we had record_in and record_out in their current form
then.
