Right.

I was thinking about that earlier. Right now there is no other way.
We could consider adding a column to pg_type to link to the array type,
but I'm not sure it's worth the trouble. I think if you look around,
there's probably already a subroutine someplace that does the lookup
using the '_foo' approach.
