Replication uses 8 bytes to store SQL_MODE in the binary log. The day you
403
use strictly more than 64 bits by adding one more define above, you should
404
contact the replication team because the replication code should then be
405
updated (to store more bytes on disk).
407
NOTE: When adding new SQL_MODE types, make sure to also add them to
408
the scripts used for creating the MySQL system tables
409
in scripts/mysql_system_tables.sql and scripts/mysql_system_tables_fix.sql
