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.
