Fluentnhibernate and PostgerSQL, SchemaMetadataUpdater.QuoteTableAndColumns - System.NotSupportedException: Specified method is not supported.

Hello! I'm using fluentnhibernate with PostgreSQL. PosrgreSQL version is 8.4.
My code for create ISessionFactory:

public static ISessionFactory CreateSessionFactory()
{
        string connectionString = ConfigurationManager.ConnectionStrings["PostgreConnectionString"].ConnectionString;
        IPersistenceConfigurer config = PostgreSQLConfiguration.PostgreSQL82.ConnectionString(connectionString);

        FluentConfiguration configuration = Fluently
            .Configure()
            .Database(config)
            .Mappings(m =>
                m.FluentMappings.Add(typeof(ResourceMap))                                    
                                .Add(typeof(TaskMap))
                                .Add(typeof(PluginMap)));
        var nhibConfig = configuration.BuildConfiguration();
        SchemaMetadataUpdater.QuoteTableAndColumns(nhibConfig);
        return configuration.BuildSessionFactory();
}

For auto-quote I was added method SchemaMetadataUpdater.QuoteTableAndColumns(nhibConfig);
When I'm execute code at line SchemaMetadataUpdater.QuoteTableAndColumns(nhibConfig); throw error: System.NotSupportedException: Specified method is not supported. Help me, please! I'm very need for solution.
Best regards
