'PROCESSLIST_STATE' FOR SLAVE SQL
Problem:
SQL thread's idle state message (Slave has read all relay
log; waiting for the slave I/O thread to update it) is 75
chars length. But performance_schema.threads 
processlist_state column is defined as char(64). When SQL
thread is instrumented and 75 chars state message is
inserted into this varchar(64) column. Server will generate
either warning/error depends on sql_mode empty or
'strict_all_tables'.                                        
Fix: Truncate the state message to 64 chars before inserting
into the column (No Warning/No error).
