Using & - operator

Hi,

I have table users;

id name bin
--------------
1 xx 9

dec(1) & dec(9) = dec(1)
bin(0001) & bin(1001) = bin(0001)

This query is bad.

SELECT name FROM users WHERE id_user=1 AND (bin & 1)

This query return
"Warning: PostgreSQL query failed: ERROR: right- hand side of AND is
type 'integer', not 'boolean' in"

Wow I write corect this query ?

Thanks.
