Prepare Statement - Mailing list pgsql-jdbc

Hi,

I have a question about performance, in SQL commands: there is a
prepare/execute command, document says it will improve the performance
while repeatly execute a statement. In java.sql: there is a
PreparedStatement object, which can store precompiled SQL statement,
document says it can improve the performance also.
If I use java jdbc to connect postgresql database, which one I should
use? Can I use both?


Thanks.
