Bug #83030 AUTO_INCREMENT not updated when using REPLACE INTO
Description:
The table AUTO_INCREMENT value is not kept in synch between the master and the slave when using REPLACE INTO.
How to repeat:
CREATE TABLE `monty` (
`id` int unsigned NOT NULL AUTO_INCREMENT,
`stub` char(15) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `stub` (`stub`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC;
INSERT INTO monty SET stub = 'foo';
INSERT INTO monty SET stub = 'bar';
Master
mysql> SELECT @@binlog_format;
+-----------------+
| @@binlog_format |
+-----------------+
| ROW |

1 row in set (0.00 sec)

Observe that the table AUTO_INCREMENT is 5 on the master and 3 on the slave.
