innodb stats tables

[Max Bubenick]

Hi All,

I would like to know if it is a good idea to change the default behavior of mydumper or myloader to not dump/load mysql special tables like mysql.innodb_index_stats (eventually with an option --force-all-tables to avoid the filter).

This solution would avoid useless dumps, and avoid this kind of errors :

=============
** (myloader:24094): CRITICAL **: Error restoring mysql.innodb_index_stats from file mysql.innodb_index_stats.sql.gz: Duplicate entry 'dailysales-tSalesReportingConsult-PRIMARY-n_diff_pfx01' for key 'PRIMARY'

** (myloader:24094): CRITICAL **: Error restoring mysql.innodb_table_stats from file mysql.innodb_table_stats.sql.gz: Duplicate entry 'dailysales-tSalesReportingConsult' for key 'PRIMARY'
=============

I'm ready to make the patch myself and post it as a blueprint if you find that a good idea.

Please tell me your thought.
