Igor Babaev	f549f495f7	Removed the server option --stat-tables. ... Renamed the system variable optimizer_use_stat_tables to use_stat_tables. This variable now has only 3 possible values: 'never', 'complementary', 'preferably'. If the server has been launched with --use-stat-tables='complementary'|'preferably' then the statictics tables can be employed by the optimizer and by the ANALYZE command.	2012-06-02 17:19:01 -07:00
