how to insert '\\' in postgres using java

[ketandba]

Hi,
all,
i have problem in postgres db insert..

Here is my problem.
i have created table like..
1)

  Create table tab1(usr_id varchar(15), usr_name varchar(20),usr_filename_pattern varchar(1024));

      insert table tab1 values('A','Mr. A','A\\d\\d\\d\\d');

Record is successfully inserted But when i retrieve using java program..
select * from tab1;
The output is 'A', 'Mr. A', 'A\d\d\d\d' (means it escapeing '\')
Also when i update the record

     update tab1 set usr_name='Mr. B' where usr_id='A';

and after succefully updation when i try to retrieve record by
select * from tab1;
output is 'A','Mr. B', 'Adddd' (means it escapeing '\' again)


My question :

After updation how i get

'A', 'Mr. B', 'A\\d\\d\\d\\d'

i.e. not escapeing '\\'.
I am using postgres 7.4.6 and java 1.4.

pl. help me out...

Thanks in advanced..
