 Description
 
 Formats a normalized statement, truncating it if it is > 64 characters long by default.
 
 To configure the length to truncate the statement to by default, update the `statement_truncate_len`
 variable with `sys_config` table to a different value. Alternatively, to change it just for just 
 your particular session, use `SET @sys.statement_truncate_len := <some new value>`.
 
 Useful for printing statement related data from Performance Schema from 
 the command line.
 
 Parameters
 
 statement (LONGTEXT): 
 The statement to format.
 
 Returns
 
 LONGTEXT
 
 Example
 
 mysql> SELECT sys.format_statement(digest_text)
 ->   FROM performance_schema.events_statements_summary_by_digest
 ->  ORDER by sum_timer_wait DESC limit 5;
