Performance schema tables are local to a server and they should not
be allowed to be executed by the slave from the relay log.
From 5.6.10, P_S events are not written into the binary log.
But prior to that, from mysql 5.5 onwards, P_S events are written
to the binary log by master.
The following are problematic scenarios:
1. Master 5.5 -> Slave 5.5
========================
A) RBR: Slave crashes
B) SBR: P_S statements are replicated.
2.Master 5.5 -> Slave 5.6
========================
A) RBR: SQL thd generates error
B) SBR : P_S statements are replicated
3. 5.5 binlog executed on a server 5.5 using mysqlbinlog|mysql
=================================================================
A) RBR: Server crash (because of BINLOG'... statement)
B) SBR: P_S statements are executed
4. 5.5 binlog executed on server 5.6 using mysqlbinlog|mysql
================================================================
A) RBR: SQL error (because of BINLOG'... statement)
B) SBR: P_S statements are executed.
The generalized behaviour should be:
a) Slave SQL thread should certainly ignore P_S events read from
the relay log.
b) mysqlbinlog|mysql should replay the binlog succesfully.
