commit    d95cecac8ae73e735dee30ef6697b3d1adac2d52
Author:   Tatsuo Ishii <ishii@postgresql.org>
Date:     Sat Mar 03 02:54:29 2012 +0000

    Fix pool_start_query() so that it uses my_master_node_id for initial
    virtual_master_node_id. Real master node could be changed while pgpool
    is running in streaming replication mode. Before it assigned
    REAL_MASTER_NODE_ID, which could have no connections after fail over
    and cause segafult because there's no connection to it.
