If you don't change change the values of the usr_filename_pattern in
the update (in the SET clause), those values should not change.
test=# select * from tab1;
usr_id | usr_name | usr_filename_pattern
--------+----------+----------------------
A | Mr. A | A\d\d\d\d
A | Mr. B | A\\d\\d\\d\\d
(2 rows)
test=# update tab1 set usr_name = 'Mr. C' where usr_id = 'A';
UPDATE 2
test=# select * from tab1;
usr_id | usr_name | usr_filename_pattern
--------+----------+----------------------
A | Mr. C | A\d\d\d\d
A | Mr. C | A\\d\\d\\d\\d
I suspect there is some additional SQL code being executed by your
Java application. You may want to enable query logging and check the
PostgreSQL logs to see exactly what queries are being executed.
