commit    6f2b4b1df869829635d4a45f47a734c11fded00e
Author:   Bo Peng <pengbo@sraoss.co.jp>
Date:     Tue Oct 09 00:20:39 2018 +0000

    Fix memory leak when memory_cache_enabled = on and write SQLs are sent.
    
    In a explicit transaction, we the SELECT results are cached in temporary buffer.
    If a write SQL is sent which modifies the table, the temporary buffe should be reset.
