commit    0b125118baec71e4345bc373f83fc696c64446f8
Author:   Tatsuo Ishii <ishii@postgresql.org>
Date:     Tue Mar 06 13:22:18 2012 +0000

    Make nodeToString() to return null terminated string.  Despite the
    naming of pool_string family, they never guarantee null terminated
    string. So we modify nodeToString() to ensure it returns null
    terminated string. This will make nodeToString users more robust.
