queries against CIDR fail against 8.0.3? - Mailing list pgsql-jdbc

Greetings,

I have a web application which is running against PG 7.3.9 and seems to
work without a problem.  Recently, I have been trying to run it against
8.0.3.  In both cases, I am using the jdbc3-8.0-312 driver.

The application fails when running against 8.0.3 at this query.

PreparedStatement s = dbConn.prepareStatement(
"SELECT * FROM institution WHERE ( institution.network >>=  ? ) LIMIT 1" );
s.setObject( 1, (String)request.getRemoteAddr() );
if( s.execute() )
{
    ...
}

DEBUG http-8180-Processor25 net.fitne.vlrc.actions.IndexAction - ERROR:
operator does not exist: cidr >>= character varying
net.ev.dao.DAOException: ERROR: operator does not exist: cidr >>=
character varying
         at net.ev.dao.DatabaseDAO.executeStatement(DatabaseDAO.java:656)
         at net.ev.dao.DatabaseDAO.find(DatabaseDAO.java:1199)

Does anyone have any ideas on how to address this issue?  Or at least an
explanation as to why it works in 7.3.9 but not 8.0.3?

Thanks in advance,
Russ
