Bug#25813089 - CREATE USER IF NOT EXISTS SHOULD ALWAYS BE
 WRITTEN TO THE BINLOGS DESCRIPTION =========== MySQL 5.7 introduced a new command CREATE USER IF NOT EXISTS ... The idea of this command is that it can be run safely on a master and would not break things irrespective of whether the user exists on the master or on the slave. However, the implementation does not write this statement to the binlog when the user exists on the master which results in an inconsistency. ANALYSIS ======== Presently, if the statements CREATE USER IF NOT EXISTS are a no-op on the master, they are not written to the the binlog. This results in an inconsistent behavior if a particular user is present on the slave but not on the master. Similar issue arises for ALTER USER IF EXISTS statements. FIX === The fix ensures that the statements having queries like 1. CREATE USER IF NOT EXISTS .. and 2. ALTER USER IF EXISTS .. are binlogged making sure that replication does not break and the consistency is maintained across all masters and slaves.
