[ADMIN] relation already exists?

[JT Kirkpatrick]

i had a table, ap (had a primary key constraint named appk), which i 
renamed ap2.  i then re-created a table named ap, with the same primary key 
constraint name appk, which postgres told me already existed.  so i dropped 
index appk, it said fine, dropped.  so i recreated table ap.  now it is 
telling me that ERROR: ap relation already exists.  i have no table named 
ap, nor any index appk.  how do i correct this?
