type creates broken view, which can't be deleted

It looks like there's a bug that allows you to create views with columns of type unknown, and then prevents you from dropping the view/table.

alpha_2=> \i brokenview
CREATE VIEW article_contrib_info AS
SELECT ac.article_id,
p,firstname, -- TYPO HERE, USED COMMA INSTEAD OF PERIOD
p.lastname
FROM person p, article_contributor ac
WHERE ac.person_id = p.person_id;
NOTICE: create: attribute named "p" has an unknown type
NOTICE: unknown node tag 704 in OffsetVarNodes()
NOTICE: Node is: { IDENT "p" }
NOTICE: copyObject: don't know how to copy 704
CREATE
alpha_2=> \d article_contrib_info

Table    = article_contrib_info
+----------------------------------+----------------------------------+-------+
|              Field               |              Type                | Length|
+----------------------------------+----------------------------------+-------+
| article_id                       | int4                             |     4 |
| p                                | unknown                          |   var |
| firstname                        | varchar()                        |     0 |
| lastname                         | varchar()                        |     0 |
+----------------------------------+----------------------------------+-------+

alpha_2=> drop view article_contrib_info;
ERROR: badly formatted planstring "IDENT "p" "...

alpha_2=> drop table article_contrib_info;
ERROR: badly formatted planstring "IDENT "p" "...

alpha_2=>

Has anyone else heard of this behavior? Is it a documented bug? Or am I missing something obvious about how to resolve this kind of problem?
