Actually the real issue was, while creating table in PostgreSQL, I used character(n) type for login_id and passwd columns, which actually will padd spaces at the end of login_id and passwd string to fill it upto n. Changing datatype of these columns to character varying (n) solves the problem. Hope this saves time for someone.
