Exactly, that's what I'm getting

Here's what I get (there really is a RowDescription(6)):

Oops, looking closer I see what you mean, that's actually 2 columns of the
> surrounding type - street + zip?

Yes, exactly. Somehow the driver stops at the second type element of the
surrounding type. This may be correlated to the fact that the inner type has
exactly 2 elements?

The other 5 columns are reported as null (always).
In pgAdmin III, I correctly get a single column in the result set. Also, the
postgres information_schema only holds one parameter:

===================================
select parameter_mode, parameter_name, udt_name
from information_schema.parameters
where specific_name like 'p_enhance_address2%'

yields:

"OUT";"address";"u_address_type"
===================================
