# BUG#43579 mysql_upgrade tries to alter log tables on replicated database
# Master and slave should be upgraded separately.  All statements executed by
# mysql_upgrade will not be binlogged. --write-binlog and --skip-write-binlog
# options are added into mysql_upgrade. These options control whether sql
# statements are binlogged or not.
