How  do I compare this dates:

1. date( in timestamp) = 2003-03-16 11:29:23.567417+08

2. date created from java program like :

String format ="dd.MM.yyyy";
Date today = new Date();
SimpleDateFormat formatter = new SimpleDateFormat(format);
String todaysdate = formatter.format(today);

says the result is : todaysday = 17.03.2003

use to_date and to_char functions, refer to para 6.7 of PostgreSQL User's
Guide.

select to_char(timestamp '2003-03-16 11:29:23.567417+08','DD.MM.YYYY');
  to_char
------------
 16.03.2003
(1 row)

if that is what you wanted to know.

If you need to compare pgsql timestamp (unix time + micros)
with java.util.Date (unix time), then 
you only need the compare() method.
Note that java.sql.Timestamp extends java.util.Date.
