Обсуждение: Converting int4 to varchar

I'm doing something very typical: I created a sequence "seq" and then
wanted to insert the NEXTVAL('seq') into a varchar field of a table to be
used as a primary key.

INSERT INTO products (prodno, ...) VALUES (NEXTVAL('seq'), 'blah',
'blah');

Where prodno is varchar. I tried a text(...) cast, but it complains of a
text-varchar mismatch. There is no varchar(...).

Apparently, this is not possible in Postgres(?).
