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 https://dev.mysql.com/doc/refman/8.0/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.
To execute BINLOG statements when applying mysqlbinlog output, a user
account requires the BINLOG_ADMIN privilege (or the deprecated SUPER
privilege), or the REPLICATION_APPLIER privilege plus the appropriate
privileges to execute each log event.
