Trouble with pg_encoding_to_char

Hi,

I've been developing a program with the postgres jdbc 2 driver, jdk-1.3.0 and
postgres 6.5.

When I start my program up it bombs like so:

Something unusual has occured to cause the driver to fail. Please report
this exception: Exception: java.sql.SQLException: ERROR: No such
function 'pg_encoding_to_char' with the specified attributes

Stack Trace:

java.sql.SQLException: ERROR: No such function 'pg_encoding_to_char'
with the specified attributes

at
org.postgresql.core.QueryExecutor.execute(QueryExecutor.java:94)
at org.postgresql.Connection.ExecSQL(Connection.java:398)
at org.postgresql.Connection.ExecSQL(Connection.java:381)
at org.postgresql.Connection.openConnection(Connection.java:314)
at org.postgresql.Driver.connect(Driver.java:149)

Does anyone know what any of this means...?

Regards,
Youenn
