You should use the sequence as parameter to currval(), like:

=> \d products
Table "public.products"
-[ RECORD 1 ]----------------------------------------------------------
Column    | proid
Type      | integer
Modifiers | not null default nextval('public.products_proid_seq'::text)
=> SELECT currval(products.proid);
ERROR:  relation "1" does not exist
=> SELECT currval('public.products_proid_seq'::text);
nextval
---------
      7
(1 row)

Regards.
