BINLOG 'str'

BINLOG is an internal-use statement. It is generated by the mysqlbinlog
program as the printable representation of certain events in binary log
files. (See http://dev.mysql.com/doc/refman/5.7/en/mysqlbinlog.html.)
The 'str' value is a base 64-encoded string the that server decodes to
determine the data change indicated by the corresponding event. This
statement requires the SUPER privilege.
