Bug with ALTER TABLE

I've discovered a bug in ALTER TABLE behaviour when it comes to
renaming a view.

I'm not sure if renaming a view is supported but Postgres will let you
do it with ALTER TABLE aview RENAME TO aview2; SELECT operations still
work on the resulting view after this command but a dump or \d aview2
will now print out :

oldplumbing=# \d t
View "t"
Attribute | Type | Modifier
------------+-------------------+----------
?column? | text |
address | character varying |
builder | character varying |
subdiv | character varying |
plan_# | character varying |
sched_date | date |
plan_id | integer |
View definition: Not a view

This is obviously not correct.
