Bug in getIndexInfo() with 9.0 JDBC driver

Hello,

in my program I'm using DatabaseMetaData.getIndexInfo().

This is working fine with the 8.4 driver on a 8.4 and 9.0 database.

However when using the 9.0 driver (postgresql-9.0-801.jdbc4.jar) I'm getting the following exception when calling
getIndexInfo():

ERROR: argument to pg_get_expr() must come from system catalogs [SQL State=42501]
org.postgresql.util.PSQLException: ERROR: argument to pg_get_expr() must come from system catalogs

         at org.postgresql.jdbc2.AbstractJdbc2DatabaseMetaData.getIndexInfo(AbstractJdbc2DatabaseMetaData.java:4023)


This is the code that I'm running (error checking removed)


Class.forName("org.postgresql.Driver");
Connection con = DriverManager.getConnection("jdbc:postgresql://localhost/postgres", "postgres", "postgres");
ResultSet rs = con.getMetaData().getIndexInfo(null, "public", "mytable", false, false);
while (rs.next())
{
    System.out.println(rs.getString("INDEX_NAME"));
}

Thanks
