Okay, I guess I'm not so curious, thanks to
http://www.postgresql.org/docs/8.0/static/sql-expressions.html#SQL-
SYNTAX-TYPE-CASTS, which tells me:

"A cast applied to an unadorned string literal represents the initial
assignment of a type to a literal constant value, and so it will succeed
for any type"

But, I still have my initial problem:

> test=# select translate ('YNNY', 'YN', '10')::bit varying & translate
> ('NYYN', 'YN', '10')::bit varying;
> ERROR:  cannot cast type text to bit varying

Ideas?
