commit    37789502b48542cd57ae257162f0caaeabeac53e
Author:   Tatsuo Ishii <ishii@postgresql.org>
Date:     Thu Apr 26 06:49:29 2012 +0000

    Fix pool_handle_query_cache() to switch memory context to session
    memory before calling pool_extract_table_oids_from_select_stmt()
    because it ends up with calling nodeToString().
    It is possible that global pool_memory is bogus when extended query
    is used.
