how to insert '\\' in postgres database using java

Hi,

  All, 

My name is ketan, 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..
