Обсуждение: query on PostgreSQL-JDBC driver

Hello All!
I have found the PostgreSQL - JDBC driver from the site
http://www.retep.org.uk/postgres/.
But, Iam not finding any tutorial for the same.
Can anybody tell me the name of the site where I can find both the
PostgreSQL driver and tutorial containing the examples .
With regards,
Sourabh Dixit
